Updated lodash

Changed startup time measurement to use structured logging via ILogger
instead of Console.WriteLine. This provides:
- Consistent logging format with other app messages
- Proper log level (Information)
- Structured data (ElapsedMilliseconds as named parameter)
- Better integration with logging infrastructure

Output now appears as:
info: Electron.Startup[0]
      App startup time until Electron launch: 1284 ms

+
+## Overview
+
+Electron.NET's SignalR mode includes built-in authentication to ensure that only the Electron process spawned by a specific .NET instance can connect to that instance's HTTP and SignalR endpoints.
+
+**When is this important?**
+- Multi-user Windows Server environments (Terminal Services, RDP)
+- Shared development machines with multiple users
+- Any scenario where multiple users run the same application simultaneously
+
+**What does it protect against?**
+- User A's Electron process connecting to User B's .NET backend
+- Unauthorized port scanning and connection attempts from other users
+- Accidental misconfigurations causing cross-user connections
+
+## Threat Model
+
+### The Problem
+
+When multiple users run the same Electron.NET application on a shared server:
+
+1. Each .NET process binds to a TCP port (e.g., `http://localhost:58971`)
+2. TCP ports are visible to **all users** on the machine
+3. Without authentication, User A's Electron could connect to User B's backend
+

+
+### The Solution
+
+Each .NET process generates a unique authentication token when launching Electron. Only requests with the correct token are allowed to connect.

+```

+
+### Key Steps
+
+1. **Token Generation**: .NET generates 128-bit cryptographic random GUID
+2. **Command-Line Passing**: Token passed to Electron via `--authtoken` parameter
+3. **Token Extraction**: Electron stores token in `global.authToken`
+4. **URL Appending**: Token appended to initial page and SignalR connection URLs
+5. **Middleware Validation**: Every HTTP request validated by middleware
+6. **Cookie Setting**: Valid token results in secure HttpOnly cookie
+7. **Cookie-Based Requests**: Subsequent requests use cookie (no token in URL)
+
+## Implementation Details
+
+### 1. Token Generation (.NET)
+
+**File**: `src/ElectronNET.AspNet/Runtime/Controllers/RuntimeControllerAspNetDotnetFirstSignalR.cs`
+
+```csharp
+private void LaunchElectron()
+{
+    // Generate secure authentication token (128-bit cryptographic random GUID)
+    this.authenticationToken = Guid.NewGuid().ToString("N"); // 32 hex chars
+    
+    // Register token with authentication service
+    this.authenticationService.SetExpectedToken(this.authenticationToken);
+    
+    // Launch Electron with token
+    var args = $"--unpackeddotnetsignalr --electronurl={this.actualUrl} --authtoken={this.authenticationToken}";
+    this.electronProcess = new ElectronProcessActive(isUnPacked, ElectronNetRuntime.ElectronExecutable, args, this.port.Value);
+    _ = this.electronProcess.Start();
+}
+```
+
+**Token Format**: 32-character hexadecimal string (e.g., `a3f8b2c1d4e5f6a7b8c9d0e1f2a3b4c5`)
+
+### 2. Authentication Service (.NET)
+
+**File**: `src/ElectronNET.AspNet/Services/ElectronAuthenticationService.cs`
+
+```csharp
+public class ElectronAuthenticationService : IElectronAuthenticationService
+{
+    private string _expectedToken;
+    private readonly object _lock = new object();
+
+    public void SetExpectedToken(string token)
+    {
+        lock (_lock)
+        {
+            _expectedToken = token;
+        }
+    }
+
+    public bool ValidateToken(string token)
+    {
+        if (string.IsNullOrEmpty(token))
+            return false;
+
+        lock (_lock)
+        {
+            if (string.IsNullOrEmpty(_expectedToken))
+                return false;
+
+            // Constant-time comparison prevents timing attacks
+            return ConstantTimeEquals(token, _expectedToken);
+        }
+    }
+
+    private static bool ConstantTimeEquals(string a, string b)
+    {
+        if (a == null || b == null || a.Length != b.Length)
+            return false;
+
+        var result = 0;
+        for (int i = 0; i < a.Length; i++)
+        {
+            result |= a[i] ^ b[i];
+        }
+        return result == 0;
+    }
+}
+```
+
+**Key Features**:
+- Thread-safe with lock
+- Constant-time comparison (prevents timing attacks)
+- Singleton lifetime (one per .NET instance)
+
+### 3. Authentication Middleware (.NET)
+
+**File**: `src/ElectronNET.AspNet/Middleware/ElectronAuthenticationMiddleware.cs`
+
+```csharp
+public async Task InvokeAsync(HttpContext context)
+{
+    // Check if authentication cookie exists
+    var authCookie = context.Request.Cookies["ElectronAuth"];
+    
+    if (!string.IsNullOrEmpty(authCookie))
+    {
+        if (_authService.ValidateToken(authCookie))
+        {
+            await _next(context);
+            return;
+        }
+        else
+        {
+            _logger.LogWarning("Invalid cookie for path {Path}", context.Request.Path);
+            context.Response.StatusCode = 401;
+            await context.Response.WriteAsync("Unauthorized: Invalid authentication");
+            return;
+        }
+    }
+
+    // No cookie - check for token in query string
+    var token = context.Request.Query["token"].ToString();
+    
+    if (!string.IsNullOrEmpty(token) && _authService.ValidateToken(token))
+    {
+        // Valid token - set cookie for future requests
+        context.Response.Cookies.Append("ElectronAuth", token, new CookieOptions
+        {
+            HttpOnly = true,
+            SameSite = SameSiteMode.Strict,
+            Path = "/",
+            Secure = false,  // localhost is HTTP
+            IsEssential = true
+        });
+        
+        await _next(context);
+        return;
+    }
+
+    // Reject - no valid cookie or token
+    context.Response.StatusCode = 401;
+    await context.Response.WriteAsync("Unauthorized: Authentication required");
+}
+```
+
+**Middleware Order** (IMPORTANT):
+```csharp
+app.UseMiddleware<ElectronAuthenticationMiddleware>();  // ← FIRST
+app.UseRouting();
+app.UseStaticFiles();
+app.UseAntiforgery();
+app.MapHub<ElectronHub>("/electron-hub");
+app.MapRazorComponents<App>();
+```
+
+### 4. Token Extraction (Electron)
+
+**File**: `src/ElectronNET.Host/main.js`
+
+```javascript
+// Extract authentication token from command-line
+if (app.commandLine.hasSwitch('authtoken')) {
+    global.authToken = app.commandLine.getSwitchValue('authtoken');
+}
+```
+
+### 5. Token in URLs (Electron)
+
+**Initial Page Load** (`src/ElectronNET.Host/api/browserWindows.js`):
+```javascript
+// Append token to window URL
+if (global.authToken) {
+    const separator = electronUrl.includes('?') ? '&' : '?';
+    electronUrl = `${electronUrl}${separator}token=${global.authToken}`;
+}
+window.loadURL(electronUrl);
+```
+
+**SignalR Connection** (`src/ElectronNET.Host/api/signalr-bridge.js`):
+```javascript
+async connect() {
+    // Append token to SignalR hub URL
+    const connectionUrl = this.authToken ? 
+        `${this.hubUrl}?token=${this.authToken}` : 
+        this.hubUrl;
+    
+    this.connection = new signalR.HubConnectionBuilder()
+        .withUrl(connectionUrl)
+        .build();
+    
+    await this.connection.start();
+}
+```
+
+### 6. Service Registration (Application)
+
+**File**: Your application's `Program.cs`
+
+```csharp
+var builder = WebApplication.CreateBuilder(args);
+
+// Register authentication service as singleton
+builder.Services.AddSingleton<IElectronAuthenticationService, ElectronAuthenticationService>();
+
+builder.Services.AddElectron();
+
+var app = builder.Build();
+
+// Register middleware BEFORE UseRouting()
+app.UseMiddleware<ElectronAuthenticationMiddleware>();
+
+app.UseRouting();
+app.MapHub<ElectronHub>("/electron-hub");
+app.Run();
+```
+
+## Security Properties
+
+### Cookie Configuration
+
+| Property | Value | Purpose |
+|----------|-------|---------|
+| `HttpOnly` | `true` | Prevents JavaScript access (XSS protection) |
+| `SameSite` | `Strict` | Prevents CSRF attacks |
+| `Path` | `/` | Cookie sent with all requests |
+| `Secure` | `false` | Cannot use on localhost HTTP |
+| `IsEssential` | `true` | Required for app to function |
+| **Lifetime** | Session | Expires when Electron closes |
+
+### Token Properties
+
+- **Entropy**: 128 bits (2^128 possible values)
+- **Format**: 32 hexadecimal characters (GUID without hyphens)
+- **Generation**: `Guid.NewGuid()` uses cryptographically secure RNG
+- **Lifetime**: Entire application session
+- **Uniqueness**: Each .NET instance generates unique token
+
+### What's Protected
+
+✅ **All HTTP endpoints**:
+- Blazor Server pages (`/`, `/counter`, etc.)
+- Static files (`/css/app.css`, `/js/script.js`)
+- API endpoints (custom controllers)
+- SignalR hub (`/electron-hub`)
+
+✅ **Both transport modes**:
+- Initial token-based authentication (query parameter)
+- Cookie-based subsequent requests
+
+✅ **Cross-user isolation**:
+- Different users = different tokens
+- Invalid token = 401 Unauthorized
+
+### What's NOT Protected Against
+
+❌ **Same-user attacks** (by design):
+- Process memory inspection
+- Debugger attachment
+- Command-line parameter visibility
+
+**Rationale**: A malicious process running as the same user already has full access to:
+- Process memory (can read token from RAM)
+- Cookies (stored in Electron's data directory)
+- All files owned by the user
+
+Token-based authentication focuses on **cross-user isolation**, not same-user security.
+
+## Troubleshooting
+
+### Problem: 401 Unauthorized on Initial Load
+
+**Symptoms**:
+```
+GET / HTTP/1.1
+Response: 401 Unauthorized
+```
+
+**Possible Causes**:
+1. Token not passed to Electron
+2. Token not appended to URL
+3. Middleware rejecting valid token
+
+**Debugging Steps**:
+
+1. Check Electron command-line:
+   ```javascript
+   console.log('Auth Token:', global.authToken);
+   ```
+   Should print 32-character hex string.
+
+2. Check URL in browser window:
+   ```javascript
+   console.log('Loading URL:', electronUrl);
+   ```
+   Should include `?token=<guid>` parameter.
+
+3. Check .NET logs:
+   ```
+   [Warning] Authentication failed: Invalid token (prefix: a3f8b2c1...)
+   ```
+
+4. Verify middleware registration:
+   ```csharp
+   app.UseMiddleware<ElectronAuthenticationMiddleware>(); // Before UseRouting()
+   ```
+
+### Problem: SignalR Connection Fails
+
+**Symptoms**:
+```
+[SignalRBridge] Authentication failed: The authentication token is invalid or missing.
+```
+
+**Possible Causes**:
+1. Token not passed to `SignalRBridge` constructor
+2. Token not appended to hub URL
+3. Cookie not being sent
+
+**Debugging Steps**:
+
+1. Check token passed to SignalRBridge:
+   ```javascript
+   console.log('SignalRBridge token:', this.authToken);
+   ```
+
+2. Check connection URL:
+   ```javascript
+   console.log('Hub URL:', connectionUrl);
+   ```
+   Should be `http://localhost:PORT/electron-hub?token=<guid>`.
+
+3. Enable verbose logging:
+   ```javascript
+   .configureLogging(signalR.LogLevel.Debug)
+   ```
+
+### Problem: Cookie Not Persisting
+
+**Symptoms**: Every request includes token in URL, cookie never set.
+
+**Possible Causes**:
+1. Cookie settings incompatible with browser
+2. Middleware not setting cookie
+3. Response headers not sent
+
+**Debugging Steps**:
+
+1. Check response headers:
+   ```
+   Set-Cookie: ElectronAuth=a3f8b2c1...; Path=/; HttpOnly; SameSite=Strict
+   ```
+
+2. Check subsequent requests:
+   ```
+   Cookie: ElectronAuth=a3f8b2c1...
+   ```
+
+3. Enable middleware logging:
+   ```csharp
+   _logger.LogInformation("Setting cookie for path {Path}", path);
+   ```
+
+### Problem: Token Visible in Process List
+
+**Observation**:
+```powershell
+wmic process where "name='electron.exe'" get commandline
+...--authtoken=a3f8b2c1d4e5f6a7b8c9d0e1f2a3b4c5...
+```
+
+**Is this a problem?** No, by design.
+
+**Explanation**:
+- Command-line parameters are visible to same-user processes
+- This is acceptable because:
+  - Same user already has access to process memory
+  - Same user can read cookies from Electron's data directory
+  - Token-based auth protects against **other users**, not same-user processes
+
+**If you need same-user protection**: Use OS-level access controls (file permissions, process isolation) or consider named pipes with ACLs.
+
+## FAQ
+
+### Q: Why use tokens instead of Process ID validation?
+
+**A**: PIDs can be recycled and reused, making validation unreliable. Additionally:
+- PIDs don't provide cryptographic security
+- Parent-child validation is platform-specific
+- Adds complexity without meaningful security benefit
+
+Token-based authentication provides:
+- Cryptographic randomness (128-bit entropy)
+- Simple cross-platform implementation
+- No race conditions or PID recycling issues
+
+### Q: Why not use HTTPS with certificates?
+
+**A**: Localhost doesn't support HTTPS certificates easily:
+- Self-signed certificates trigger browser warnings
+- Certificate management adds complexity
+- Token-based auth provides equivalent security for localhost IPC
+
+### Q: Can I disable authentication?
+
+**A**: Not recommended, but possible by removing middleware registration:
+
+```csharp
+// Remove this line:
+// app.UseMiddleware<ElectronAuthenticationMiddleware>();
+```
+
+**Warning**: Only do this if:
+- Application runs on single-user machines only
+- No Terminal Services / RDP access
+- You understand the security implications
+
+### Q: Does this work with hot reload?
+
+**A**: Yes, cookie persists across hot reload as long as Electron process keeps running.
+
+### Q: What about multiple Electron windows?
+
+**A**: All windows in the same Electron process share cookies automatically. Authentication works seamlessly across multiple windows.
+
+### Q: How do I test authentication?
+
+**Test 1 - Happy Path**:
+1. Run application normally
+2. Check logs for "Authentication successful"
+3. Verify cookie is set (DevTools → Application → Cookies)
+4. Subsequent requests should not include token in URL
+
+**Test 2 - Invalid Token**:
+1. Modify token in browser URL: `?token=invalid`
+2. Should receive 401 Unauthorized
+3. Check logs for "Authentication failed: Invalid token"
+
+**Test 3 - No Token**:
+1. Open browser manually to `http://localhost:PORT/`
+2. Should receive 401 Unauthorized
+3. Check logs for "Authentication failed: No cookie or token"
+
+**Test 4 - Multi-User** (Windows Server/Terminal Services):
+1. Launch app as User A
+2. In User B session, try to connect to User A's port
+3. Should receive 401 Unauthorized
+
+### Q: What about packaged applications?
+
+**A**: Authentication works identically in packaged mode. The `--authtoken` parameter is included in the packaged Electron executable.
+
+### Q: Can I customize the cookie name?
+
+**A**: Yes, modify `AuthCookieName` constant in `ElectronAuthenticationMiddleware.cs`:
+
+```csharp
+private const string AuthCookieName = "MyCustomCookieName";
+```
+
+## Summary
+
+Electron.NET's token-based authentication provides:
+
+✅ **Security**: 128-bit entropy, constant-time comparison, secure cookies  
+✅ **Simplicity**: Automatic token generation and validation  
+✅ **Compatibility**: Works with Blazor, SignalR, and static files  
+✅ **Monitoring**: Structured logging for security events  
+✅ **Multi-User**: Cross-user isolation on shared servers  
+
+The authentication system is **enabled by default** in SignalR mode and requires minimal configuration. For most applications, simply register the services and middleware - everything else happens automatically.

+# SignalR Implementation Summary
+
+This document summarizes the completed implementation of SignalR-based bidirectional communication in Electron.NET as an alternative to Socket.IO.
+
+## Overview
+
+The SignalR implementation provides a modern, .NET-native alternative to Socket.IO for communication between the ASP.NET Core host and the Electron process. This new startup mode was designed specifically for **Blazor Server applications** where ASP.NET Core and Electron need tighter integration and lifecycle control.
+
+**Key Innovation**: .NET-first startup with dynamic port assignment - ASP.NET Core starts first, binds to port 0 (letting Kestrel choose an available port), then launches Electron with the actual URL.
+
+## Primary Use Case
+
+Blazor Server applications where:
+- ASP.NET Core owns the application lifecycle
+- Dynamic port binding is needed (no fixed port configuration)
+- Modern SignalR infrastructure is preferred over Socket.IO
+- Single process debugging is desired (.NET process controls Electron)
+
+## Implementation Phases (All Complete)
+
+### Phase 1: Core Infrastructure ✅
+- Added new `StartupMethod` enum values:
+  - `UnpackagedDotnetFirstSignalR` 
+  - `PackagedDotnetFirstSignalR`
+- Created `ElectronHub` SignalR hub for bidirectional communication
+- Registered hub endpoint at `/electron-hub` (separate from Blazor's `/_blazor` hub)
+
+### Phase 2: Runtime Controller ✅
+- Created `RuntimeControllerAspNetDotnetFirstSignalR`
+- Implemented logic to:
+  - Bind Kestrel to port 0
+  - Wait for Kestrel startup and capture actual port via `IServerAddressesFeature`
+  - Launch Electron with `--electronurl` parameter
+  - Wait for SignalR connection from Electron
+  - Transition to Ready state when connected
+
+### Phase 3: Electron/Node.js Side ✅
+- Added `@microsoft/signalr` npm package dependency
+- Created SignalR connection module (`signalr-bridge.js`)
+- Updated `main.js` to detect SignalR modes and connect to `/electron-hub`
+- Implemented Socket.IO-compatible interface for API compatibility
+
+### Phase 4: API Bridge Adaptation ✅
+- Created `SignalRFacade` implementing `IFacade` interface
+- Ensured existing Electron API classes work with SignalR
+- Implemented type conversion helper for SignalR's JSON deserialization
+- Event routing from both directions (.NET ↔ Electron)
+
+### Phase 5: Configuration & Extensions ✅
+- Updated `WebHostBuilderExtensions` for automatic SignalR configuration
+- Added startup mode detection via command-line flags
+- Configured dynamic port binding (port 0) for SignalR modes
+- Integrated with `UseElectron()` API for seamless usage
+
+### Phase 6: Testing & Fixes ✅
+- Created sample Blazor Server application
+- Fixed multiple critical issues discovered during integration testing
+- Cleaned up debug logging
+- Added comprehensive code documentation
+
+## Key Components
+
+### 1. SignalRFacade (`src/ElectronNET.AspNet/Bridge/SignalRFacade.cs`)
+- Implements `IFacade` interface to match Socket.IO facade API
+- Handles bidirectional event routing using `IHubContext<ElectronHub>`
+- Includes `ConvertToType<T>` helper for handling SignalR's JSON deserialization quirks
+- Critical fix: Handles `JsonElement` and numeric type conversions (long → int)
+
+### 2. ElectronHub (`src/ElectronNET.AspNet/Hubs/ElectronHub.cs`)
+- SignalR hub for .NET ↔ Electron communication
+- Key methods:
+  - `RegisterElectronClient()` - Called by Electron on connection
+  - `ElectronEvent(string, object[])` - Receives events from Electron
+  - Connection/disconnection handlers notify runtime controller
+
+### 3. RuntimeControllerAspNetDotnetFirstSignalR
+- Manages SignalR mode lifecycle
+- Critical flow:
+  1. Wait for ASP.NET server to start
+  2. Capture dynamic port from `IServerAddressesFeature`
+  3. Update `ElectronNetRuntime.AspNetWebPort` with actual port
+  4. Launch Electron with `--electronurl` parameter
+  5. Wait for `electron-host-ready` signal before calling app ready callback
+
+### 4. SignalRBridge (`src/ElectronNET.Host/api/signalr-bridge.js`)
+- JavaScript SignalR client that mimics Socket.IO interface
+- Provides `on()` and `emit()` methods for API compatibility
+- Critical fix: Event args passed as arrays, spread when calling handlers
+- Uses `@microsoft/signalr` npm package
+
+### 5. Main.js Startup (`src/ElectronNET.Host/main.js`)
+- Detects SignalR mode via `--unpackeddotnetsignalr` or `--dotnetpackedsignalr` flags
+- Creates invisible keep-alive window (destroyed when first real window is created)
+- Loads API modules then signals `electron-host-ready` to .NET
+
+## Usage
+
+Enable SignalR mode by passing the appropriate command-line flag:
+
+```bash
+# Unpacked mode (development)
+dotnet run --unpackeddotnetsignalr
+
+# Packed mode (production)
+dotnet run --dotnetpackedsignalr
+```
+
+Or set environment variable (deprecated, flags preferred):
+```bash
+ELECTRON_USE_SIGNALR=true
+```
+
+In your ASP.NET Core Program.cs:
+
+```csharp
+var builder = WebApplication.CreateBuilder(args);
+
+// Add Electron.NET services
+builder.Services.AddElectron();
+
+// Configure Electron with SignalR mode
+builder.WebHost.UseElectron(args, async () =>
+{
+    var window = await Electron.WindowManager.CreateWindowAsync();
+    window.OnReadyToShow += () => window.Show();
+});
+
+var app = builder.Build();
+
+app.UseRouting();
+
+// Map SignalR hub for Electron communication
+app.MapHub<ElectronHub>("/electron-hub");
+
+app.MapRazorComponents<App>().AddInteractiveServerRenderMode();
+app.Run();
+```
+
+**Note**: `UseElectron()` automatically detects SignalR mode and configures everything. The rest happens automatically:
+1. Port 0 binding (dynamic port assignment)
+2. Electron launch with actual URL
+3. SignalR connection establishment (WebSockets enabled automatically by MapHub)
+4. App ready callback execution
+2. Electron launch with actual URL
+3. SignalR connection establishment (WebSockets enabled automatically by `MapHub`)
+4. App ready callback execution
+
+## Architecture Decisions
+
+### Why .NET-First Startup?
+SignalR mode uses .NET-first startup (vs. Electron-first in Socket.IO mode) because:
+1. **No port scanning needed** - .NET can pass the actual URL to Electron
+2. **SignalR hub must be registered** before Electron connects
+3. **Simpler lifecycle** - ASP.NET controls when Electron launches
+4. **Better for Blazor Server** - Blazor is already running when Electron starts
+5. **Single process debugging** - Developer debugs .NET process which owns Electron
+
+### Why IFacade Interface?
+Introducing `IFacade` allows `BridgeConnector.Socket` to return either `SocketIOFacade` or `SignalRFacade` based on startup mode, ensuring existing API code works with both transport mechanisms without modification.
+
+### Why Keep-Alive Window?
+Electron quits immediately on macOS if no windows exist. The keep-alive window ensures Electron stays running during the connection and API initialization phase. It's automatically destroyed when the first real window is created.
+
+### Why 'electron-host-ready' Signal?
+Without this signal, .NET would call the app ready callback before Electron finished loading API modules, causing API calls to fail. The signal ensures proper initialization order:
+1. Electron connects to SignalR
+2. Electron loads all API modules (browserWindows, dialog, menu, etc.)
+3. Electron signals `electron-host-ready`
+4. .NET calls app ready callback
+5. App code can safely use Electron APIs
+
+## Blazor Server Considerations
+
+### SignalR Hub Coexistence
+Blazor Server already uses SignalR for component communication (`/_blazor` hub). Our implementation:
+- Uses separate endpoint (`/electron-hub`) to avoid conflicts
+- Both hubs coexist on the same Kestrel server without interference
+- No impact on Blazor's reconnection logic
+- Compatible with hot reload scenarios
+
+### Lifecycle Integration
+- Electron window creation happens **after** Blazor app is ready
+- `UseElectron()` callback fires when SignalR hub is connected
+- Blazor components can inject Electron services to control windows
+- Proper disposal when Electron process exits
+
+### Development Experience
+- Hot reload works for both Blazor and Electron integration
+- F5 debugging works seamlessly
+- No need to manually coordinate ports
+- Single process to debug (.NET process owns the lifecycle)
+
+## Critical Fixes Applied
+
+### 1. Race Condition: API Module Loading
+**Problem**: .NET called app ready callback before Electron finished loading API modules.
+
+**Solution**: Electron signals `electron-host-ready` after loading all API modules. .NET waits for this signal before calling the app ready callback.
+
+### 2. Event Argument Mismatch
+**Problem**: SignalR sent event data as nested arrays `[[data]]` instead of `[data]`.
+
+**Solution**: 
+- C#: Use explicit `object[] args` parameter (not `params`)
+- JS: Always pass args as array: `invoke('ElectronEvent', eventName, args)`
+- JS: Spread args when calling handlers: `handler(...argsArray)`
+
+### 3. Type Conversion Failures
+**Problem**: SignalR deserializes JSON numbers as `JsonElement` or `long`, causing `Once<int>` handlers to fail silently.
+
+**Solution**: `SignalRFacade.ConvertToType<T>` handles JsonElement deserialization and numeric conversions.
+
+### 4. Window Shutdown Not Triggering Exit
+**Problem**: Keep-alive window prevented `window-all-closed` event from firing.
+
+**Solution**: Destroy keep-alive window when first real window is created using `app.once('browser-window-created')`.
+
+### 5. Dynamic Port Not Propagated
+**Problem**: When using port 0, Kestrel assigns a dynamic port, but `ElectronNetRuntime.AspNetWebPort` was not updated.
+
+**Solution**: Update `AspNetWebPort` after capturing port from `IServerAddressesFeature` in `CapturePortAndLaunchElectron()`.
+
+### 7. Blazor Static Files Not Loading
+**Problem**: Blazor CSS and framework files returned 404 errors.
+
+**Solution**: 
+- Added `app.UseStaticFiles()` to serve wwwroot content
+- Fixed middleware order: `UseAntiforgery()` must be between `UseRouting()` and `UseEndpoints()`
+- Updated scoped CSS asset reference to use lowercase name matching .NET 9+ convention
+
+## Authentication & Security
+
+### Token-Based Authentication (Multi-User Protection)
+
+SignalR mode includes built-in authentication to prevent unauthorized connections in multi-user scenarios (e.g., Windows Server with Terminal Services/RDP).
+
+**Threat Model**: On shared servers, multiple users can run the same application simultaneously. Without authentication, User A's Electron process could potentially connect to User B's ASP.NET backend.
+
+**Solution**: Token-based authentication with secure cookies.
+
+### Authentication Flow
+
+1. **.NET generates token**: When launching Electron, `RuntimeControllerAspNetDotnetFirstSignalR` generates a cryptographically secure GUID (128-bit entropy)
+2. **Token passed via command-line**: Electron receives `--authtoken=<guid>` parameter
+3. **Token appended to URLs**: 
+   - Initial page load: `http://localhost:PORT/?token=<guid>`
+   - SignalR connection: `http://localhost:PORT/electron-hub?token=<guid>`
+4. **Middleware validates token**: `ElectronAuthenticationMiddleware` checks every HTTP request
+5. **Cookie set on first request**: After successful token validation, secure HttpOnly cookie is set
+6. **Subsequent requests use cookie**: No token in URLs after initial authentication
+
+### Security Properties
+
+- **Cookie Settings**:
+  - `HttpOnly`: true (prevents JavaScript access, XSS protection)
+  - `SameSite`: Strict (prevents CSRF)
+  - `Path`: / (applies to all routes)
+  - `Secure`: false (localhost is HTTP, not HTTPS)
+  - `IsEssential`: true (required for app to function)
+  - **Lifetime**: Session scope (expires when Electron closes)
+
+- **Token Validation**:
+  - Constant-time string comparison (prevents timing attacks)
+  - Token stored in singleton service (one per .NET instance)
+  - Never logged in full (only first 8 characters for debugging)
+
+- **Protection Scope**:
+  - All HTTP endpoints (Blazor pages, static files, API calls)
+  - SignalR hub connection (negotiate and all hub traffic)
+  - Both initial request and cookie-based requests validated
+
+### What This Protects Against
+
+✅ **Protected**:
+- Cross-user connections (User A → User B's backend)
+- Port scanning attacks from other users
+- Accidental connections from misconfigured processes
+
+❌ **NOT Protected Against** (By Design):
+- Malicious same-user processes with debugger access
+- Process memory inspection tools (same privilege level)
+- Command-line parameter visibility (same user can see all processes)
+
+**Rationale**: Same-user attacks already have full access to process memory, files, and cookies. Token-based authentication focuses on cross-user isolation, which is the primary threat in multi-user environments.
+
+### Implementation Components
+
+1. **IElectronAuthenticationService** (`src/ElectronNET.AspNet/Services/`)
+   - Singleton service storing expected token
+   - Thread-safe with lock-based validation
+   - Constant-time comparison to prevent timing attacks
+
+2. **ElectronAuthenticationMiddleware** (`src/ElectronNET.AspNet/Middleware/`)
+   - Validates every HTTP request before routing
+   - Checks cookie first, then token query parameter
+   - Sets cookie on first valid token
+   - Returns 401 for invalid/missing authentication
+   - Structured logging for security monitoring
+
+3. **Token Generation** (`RuntimeControllerAspNetDotnetFirstSignalR.cs`)
+   - `Guid.NewGuid().ToString("N")` = 32 hex characters
+   - Called in `LaunchElectron()` method
+   - Registered with authentication service immediately
+
+4. **Electron Integration** (`main.js`, `signalr-bridge.js`)
+   - Extracts token from `--authtoken` parameter
+   - Stores in `global.authToken` for module access
+   - Appends to browser window URL and SignalR connection URL
+
+### Usage in Custom Applications
+
+Authentication is **enabled by default** in SignalR mode. No additional configuration required beyond service registration:
+
+```csharp
+var builder = WebApplication.CreateBuilder(args);
+
+// Register authentication service (singleton)
+builder.Services.AddSingleton<IElectronAuthenticationService, ElectronAuthenticationService>();
+
+builder.Services.AddElectron();
+
+var app = builder.Build();
+
+// Register middleware BEFORE UseRouting()
+app.UseMiddleware<ElectronAuthenticationMiddleware>();
+
+app.UseRouting();
+app.MapHub<ElectronHub>("/electron-hub");
+app.MapRazorComponents<App>().AddInteractiveServerRenderMode();
+app.Run();
+```
+
+The rest is automatic:
+- Token generation happens when Electron launches
+- Token validation happens on every request
+- Cookie management is handled by the middleware
+
+### Logging & Monitoring
+
+Authentication events are logged with structured logging:
+
+**Successful authentication**:
+```
+[Information] Authentication successful: Setting cookie for path /
+```
+
+**Failed authentication**:
+```
+[Warning] Authentication failed: Invalid token (prefix: a3f8b2c1...) for path / from 127.0.0.1
+[Warning] Authentication failed: No cookie or token provided for path /api/data from 127.0.0.1
+[Warning] Authentication failed: Invalid cookie for path /_blazor from 127.0.0.1
+```
+
+**SignalR connection failures**:
+```
+[SignalRBridge] Authentication failed: The authentication token is invalid or missing.
+[SignalRBridge] Please ensure the --authtoken parameter is correctly passed to Electron.
+```
+
+Log failed authentication attempts for security monitoring and troubleshooting.
+
+### Testing Multi-User Scenarios
+
+To test authentication in multi-user environments:
+
+1. **Run as different Windows users**:
+   ```powershell
+   # User A session
+   dotnet run
+   
+   # User B session (different RDP/Terminal Services session)
+   dotnet run
+   ```
+
+2. **Verify isolation**: User A's Electron cannot access User B's backend
+3. **Check logs**: Failed auth attempts should be logged
+4. **Monitor tokens**: Each instance generates unique token
+
+For development testing on single-user machines, simulate by running multiple instances and attempting to connect with wrong/missing tokens.
+
+## Backward Compatibility
+
+This is a **new optional startup mode** - all existing modes continue to work unchanged:
+- `PackagedElectronFirst` - unchanged
+- `PackagedDotnetFirst` - unchanged  
+- `UnpackedElectronFirst` - unchanged
+- `UnpackedDotnetFirst` - unchanged
+
+Existing applications do not need to change. SignalR mode is opt-in via command-line flags.
+
+## File Changes Summary

+
+**Total Changes**: ~1,220 lines added
+
+## Testing Recommendations
+
+1. Test with dynamic port (port 0) to ensure URL propagation works
+2. Verify window-all-closed triggers app exit
+3. Test rapid window creation/destruction
+4. Verify reconnection behavior if SignalR connection drops
+5. Test with both packed and unpacked modes
+6. Verify API calls work correctly (especially those returning data)
+
+## Known Limitations
+
+1. **Request-response pattern not yet implemented** - `InvokeElectronApi` is a placeholder. Current API calls use event-based pattern.
+2. **TouchBar API not yet supported** on macOS SignalR mode
+3. **SignalR automatic reconnection** may cause issues with pending API calls (needs circuit breaker pattern)
+
+## Future Enhancements
+
+1. **Request-response pattern** - Implement proper async/await pattern for API calls that return values
+2. **Metrics/diagnostics** - Add SignalR connection health monitoring
+3. **Circuit breaker** - Handle reconnection scenarios gracefully
+4. **Integration tests** - Comprehensive test suite for SignalR mode
+5. **Performance benchmarks** - Compare SignalR vs Socket.IO performance
+
+## Success Metrics
+
+The implementation is considered complete and functional:
+- ✅ .NET starts first with dynamic port (port 0)
+- ✅ Electron launches with actual URL
+- ✅ SignalR connection establishes successfully
+- ✅ API modules load before app ready callback
+- ✅ Window creation works from .NET
+- ✅ Window shutdown triggers app exit
+- ✅ Blazor Server pages load with correct styling
+- ✅ Both SignalR hubs coexist (Electron + Blazor)
+- ✅ Clean codebase with minimal debug logging
+- ✅ Comprehensive inline documentation
+- ✅ Token-based authentication for multi-user scenarios
+- ✅ Secure cookie-based session management
+- ✅ Structured logging for security monitoring
+- ✅ Protection against cross-user connection attempts

+# SignalR-Based Startup Mode for Electron.NET
+
+## Overview
+
+This feature adds a new startup mode for Electron.NET where:
+- **.NET/ASP.NET Core starts first** and binds to port 0 (dynamic port)
+- **Kestrel picks an available port** automatically
+- **Electron process is launched** with the actual URL
+- **SignalR is used for communication** instead of socket.io
+- **Blazor Server apps** can coexist with Electron control
+
+## Status
+
+✅ **Phases 1-5 Complete** - Infrastructure ready, basic functionality implemented
+⏸️ **Phase 6 Pending** - Full API integration, testing, and documentation
+
+## How It Works
+
+### Startup Sequence
+
+1. ASP.NET Core application starts
+2. Kestrel binds to `http://localhost:0` (random available port)
+3. `RuntimeControllerAspNetDotnetFirstSignalR` captures the actual port via `IServerAddressesFeature`
+4. Electron process is launched with `--electronUrl=http://localhost:XXXXX`
+5. Electron's main.js detects SignalR mode (via `--dotnetpackedsignalr` or `--unpackeddotnetsignalr` flag)
+6. Electron connects to SignalR hub at `/electron-hub`
+7. Hub notifies runtime controller of successful connection
+8. Application transitions to "Ready" state
+9. `ElectronAppReady` callback is invoked
+
+### Communication Flow
+
+```
+.NET/Kestrel (Port 0) ←→ SignalR Hub (/electron-hub) ←→ Electron Process
+         ↓                        ↓                           ↓
+    Blazor Server          ElectronHub class         SignalR Client
+    (/_blazor hub)         (API commands)           (main.js + signalr-bridge.js)
+```
+
+## Usage
+
+### 1. Enable SignalR Mode
+
+Set the environment variable:
+```bash
+ELECTRON_USE_SIGNALR=true
+```
+
+Or in launchSettings.json:
+```json
+{
+  "environmentVariables": {
+    "ELECTRON_USE_SIGNALR": "true"
+  }
+}
+```
+
+### 2. Configure ASP.NET Core
+
+In your `Program.cs`:
+
+```csharp
+using ElectronNET.API;
+using ElectronNET.API.Entities;
+
+var builder = WebApplication.CreateBuilder(args);
+
+builder.Services.AddRazorPages();
+builder.Services.AddElectron();
+
+builder.UseElectron(args, async () =>
+{
+    var window = await Electron.WindowManager.CreateWindowAsync(
+        new BrowserWindowOptions { Show = false });
+    
+    window.OnReadyToShow += () => window.Show();
+});
+
+var app = builder.Build();
+
+// Configure middleware
+app.UseStaticFiles();
+app.UseRouting();
+
+// Map the Electron SignalR hub
+app.MapElectronHub();  // ← Required for SignalR mode
+app.MapRazorPages();
+
+app.Run();
+```
+
+### 3. Run Your Application
+
+Just press F5 in Visual Studio or run:
+```bash
+dotnet run
+```
+
+The application will:
+- Automatically detect SignalR mode via environment variable
+- Bind Kestrel to port 0
+- Launch Electron with the correct URL
+- Establish SignalR connection
+
+## Components
+
+### .NET Side
+
+- **`ElectronHub`** - SignalR hub at `/electron-hub`
+- **`SignalRFacade`** - Mimics `SocketIoFacade` interface for compatibility
+- **`RuntimeControllerAspNetDotnetFirstSignalR`** - Lifecycle management
+- **`StartupMethod.PackagedDotnetFirstSignalR`** - For packaged apps
+- **`StartupMethod.UnpackedDotnetFirstSignalR`** - For debugging
+
+### Electron Side
+
+- **`signalr-bridge.js`** - SignalR client wrapper
+- **`main.js`** - Detects SignalR mode and connects to hub
+- **`@microsoft/signalr`** npm package
+
+## Key Features
+
+✅ **Dynamic Port Assignment** - No hardcoded ports, no conflicts  
+✅ **Blazor Server Compatible** - Separate hub endpoints (`/electron-hub` vs `/_blazor`)  
+✅ **Bidirectional Communication** - Both .NET→Electron and Electron→.NET  
+✅ **Hot Reload Support** - SignalR automatic reconnection  
+✅ **Multiple Instances** - Each instance gets its own port  
+
+## Current Limitations (Phase 6 Work Needed)
+
+⚠️ **Electron API Integration** - Existing Electron APIs (WindowManager, Dialog, etc.) still use SocketIoFacade. Full integration requires:
+- Refactoring APIs to work with both facades, or
+- Creating an adapter pattern
+
+⚠️ **Request-Response Pattern** - Current hub methods are one-way. Need to implement proper async request-response for API calls.
+
+⚠️ **Event Routing** - Electron events need to be routed through SignalR back to .NET.
+
+⚠️ **Testing** - Integration tests needed to validate end-to-end functionality.
+
+## What's Implemented

+### Phase 1: Core Infrastructure ✅
+- New `StartupMethod` enum values
+- `ElectronHub` SignalR hub
+- Hub endpoint registration
+
+### Phase 2: Runtime Controller ✅

+- Event handler system
+- Hub connection integration
+
+### Phase 5: Configuration ✅

+1. **API Integration** - Make existing Electron APIs work with SignalR
+2. **Sample Application** - Create a Blazor Server demo
+3. **Integration Tests** - Validate end-to-end scenarios
+4. **Documentation** - Complete user guides and examples
+5. **Performance Testing** - Compare with socket.io mode

+- **Performance** - SignalR is optimized for ASP.NET Core
+- **Reliability** - Built-in reconnection and error handling
+- **Scalability** - Can leverage SignalR's scale-out features
+- **Consistency** - Blazor Server already uses SignalR
+
+## Contributing
+
+To contribute to Phase 6 (full API integration):
+
+1. Focus on adapting existing Electron API classes to work with SignalRFacade
+2. Implement request-response pattern in ElectronHub
+3. Add integration tests
+4. Create sample applications
+5. Update documentation
+

+# Electron.NET Blazor SignalR Sample
+
+This sample demonstrates how to use Electron.NET with **SignalR-based startup mode** in a Blazor Server application.
+
+## Features
+
+✅ **SignalR Communication** - Uses SignalR instead of socket.io for .NET ↔ Electron communication  
+✅ **Dynamic Port Assignment** - Kestrel binds to port 0, avoiding conflicts  
+✅ **Blazor Server** - Full Blazor Server support with interactive components  
+✅ **Electron Integration** - Native desktop window with auto-hide menu bar  
+
+## Prerequisites
+
+- .NET 10.0 SDK or later
+- Node.js 22.x or later
+
+## How to Run
+
+### Method 1: Visual Studio
+
+1. Open the solution in Visual Studio
+2. Set `ElectronNET.Samples.BlazorSignalR` as the startup project
+3. Press **F5** to run
+
+The environment variable `ELECTRON_USE_SIGNALR=true` is already configured in `launchSettings.json`.
+
+### Method 2: Command Line
+
+```bash
+cd src/ElectronNET.Samples.BlazorSignalR
+set ELECTRON_USE_SIGNALR=true    # Windows
+# or
+export ELECTRON_USE_SIGNALR=true # Linux/Mac
+dotnet run
+```
+
+## What Happens
+
+1. ASP.NET Core starts with Kestrel on port 0 (random available port)
+2. Electron.NET detects `ELECTRON_USE_SIGNALR=true` environment variable
+3. Runtime controller captures the actual port (e.g., `http://localhost:54321`)
+4. Electron process is launched with `--electronUrl=http://localhost:54321`
+5. Electron connects to SignalR hub at `/electron-hub`
+6. Once connected, the `ElectronAppReady` callback fires
+7. A browser window is created showing the Blazor Server application
+8. Both Blazor's SignalR hub (`/_blazor`) and Electron's hub (`/electron-hub`) run side-by-side
+
+## Key Files
+
+- **Program.cs** - Application startup with Electron and SignalR configuration
+- **launchSettings.json** - Sets `ELECTRON_USE_SIGNALR=true` environment variable
+- **ElectronNET.Samples.BlazorSignalR.csproj** - Project configuration with Electron.NET references
+
+## Code Highlights
+
+### Program.cs
+
+```csharp
+// Configure Electron.NET with SignalR mode
+builder.WebHost.UseElectron(args, async () =>
+{
+    var options = new BrowserWindowOptions
+    {
+        Show = false,
+        Width = 1200,
+        Height = 800,
+        IsRunningBlazor = true, // Crucial for Blazor support
+    };
+
+    var browserWindow = await Electron.WindowManager.CreateWindowAsync(options);
+    browserWindow.OnReadyToShow += () => browserWindow.Show();
+});
+
+// ... configure services ...
+
+// Map the Electron SignalR hub (required for SignalR mode)
+app.MapElectronHub();
+```
+
+### launchSettings.json
+
+```json
+{
+  "environmentVariables": {
+    "ASPNETCORE_ENVIRONMENT": "Development",
+    "ELECTRON_USE_SIGNALR": "true"
+  },
+  "applicationUrl": "http://localhost:0"
+}

+## Differences from Socket.io Mode
+
+| Aspect | Socket.io Mode | SignalR Mode |
+|--------|---------------|--------------|
+| Communication | socket.io | SignalR |
+| Port Selection | Fixed port found by portscanner | Dynamic (port 0) |
+| Startup Order | Electron → .NET or .NET → Electron | .NET → Electron |
+| Hub Endpoint | N/A (socket.io on separate port) | `/electron-hub` |
+| Environment Variable | None | `ELECTRON_USE_SIGNALR=true` |
+
+## Console Output
+
+When running successfully, you should see:
+
+```
+[SignalR Sample] Application configured and starting...
+[RuntimeControllerAspNetDotnetFirstSignalR] StartCore
+[RuntimeControllerAspNetDotnetFirstSignalR] URL: http://localhost:54321
+[RuntimeControllerAspNetDotnetFirstSignalR] Launching: --dotnetpackedsignalr --electronUrl=http://localhost:54321
+[RuntimeControllerAspNetDotnetFirstSignalR] Electron ready
+[SignalRBridge] Connecting to http://localhost:54321/electron-hub
+[ElectronHub] Client connected: abc123xyz
+[SignalRBridge] Connected successfully
+[RuntimeControllerAspNetDotnetFirstSignalR] SignalR connected!
+[SignalR Sample] Electron app ready callback executed!
+[SignalR Sample] Window ready and visible!
+```
+
+## Troubleshooting
+
+### Window doesn't appear
+
+- Check that `ELECTRON_USE_SIGNALR` environment variable is set
+- Look for errors in the console output
+- Verify `app.MapElectronHub()` is called in Program.cs
+
+### Connection fails
+
+- Ensure SignalR hub is properly mapped
+- Check firewall settings
+- Verify Node.js and npm packages are installed (`npm install` in ElectronNET.Host)
+
+### Hot Reload issues
+
+- SignalR supports automatic reconnection
+- If issues persist, restart the application
+
+## Next Steps
+
+- Modify the Blazor components in `Components/Pages/`
+- Add more Electron API calls in the `ElectronAppReady` callback
+- Explore bidirectional communication between Blazor and Electron
+
