+# .NET Modernization Plan: Local MariaDB Application
+
+## Overview
+Complete modernization of Marechai application from .NET 5 to .NET 9 with dependency updates and local credential security.
+
+## Goals
+1. Upgrade from .NET 5.0 to .NET 9.0
+2. Update all NuGet packages to latest compatible versions
+3. Fix security vulnerabilities (SkiaSharp CVE)
+4. Remove deprecated dependencies (Application Insights)
+5. Implement secure local credential storage using Data Protection API
+6. Maintain all MariaDB functionality and local-only architecture
+
+## Projects
+- **Marechai.Database.csproj** - Class library (net5.0 → net9.0)
+- **Marechai.csproj** - ASP.NET Core app (net5.0 → net9.0)
+
+## Migration Tasks
+
+### Task 1: Upgrade .NET Framework

+- SkiaSharp.NativeAssets.Linux: 2.80.2 → 3.119.1
+
+### Task 3: Remove Deprecated Packages
+- Microsoft.ApplicationInsights.AspNetCore: 2.16.0 (deprecated)
+
+### Task 4: Implement Local Credential Encryption
+- Add Data Protection API configuration in appsettings.json
+- Create credential encryption utility for DPAPI integration
+- Update connection string handling in Program.cs
+- Add encrypted credential support in Startup.cs
+- Ensure backward compatibility with existing deployments
+
+## Execution Order
+1. Upgrade .NET framework versions
+2. Update NuGet packages
+3. Fix security vulnerabilities
+4. Remove deprecated dependencies
+5. Implement credential encryption
+6. Comprehensive testing and validation
+7. Commit all changes
+
+## Success Criteria
+- ✅ Both projects target .NET 9.0
+- ✅ All recommended packages updated
+- ✅ SkiaSharp security vulnerability fixed

+# Shared Assets
+
+See documentation about assets here: https://github.com/unoplatform/uno/blob/master/doc/articles/features/working-with-assets.md
+
+## Here is a cheat sheet
+
+1. Add the image file to the `Assets` directory of a shared project.
+2. Set the build action to `Content`.
+3. (Recommended) Provide an asset for various scales/dpi
+
+### Examples
+
+```text
+\Assets\Images\logo.scale-100.png
+\Assets\Images\logo.scale-200.png
+\Assets\Images\logo.scale-400.png
+
+\Assets\Images\scale-100\logo.png
+\Assets\Images\scale-200\logo.png
+\Assets\Images\scale-400\logo.png
+```
+
+### Table of scales
+
+| Scale | WinUI       | iOS | Android |
+|-------|:-----------:|:---------------:|:-------:|
+| `100` | scale-100   | @1x             | mdpi    |
+| `125` | scale-125   | N/A             | N/A     |
+| `150` | scale-150   | N/A             | hdpi    |
+| `200` | scale-200   | @2x             | xhdpi   |
+| `300` | scale-300   | @3x             | xxhdpi  |
+| `400` | scale-400   | N/A             | xxxhdpi |

+To add cross-platform image assets for your Uno Platform app, use the Assets folder
+in the shared project instead. Resources in this folder are Android-only.
+
+Images, layout descriptions, binary blobs and string dictionaries can be included 
+in your application as resource files.  Various Android APIs are designed to 
+operate on the resource IDs instead of dealing with images, strings or binary blobs 
+directly.
+
+For example, a sample Android app that contains a user interface layout (main.axml),
+an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 
+would keep its resources in the "Resources" directory of the application:
+
+Resources/
+    drawable/
+        icon.png
+
+    layout/
+        main.axml
+
+    values/
+        strings.xml
+
+In order to get the build system to recognize Android resources, set the build action to
+"AndroidResource".  The native Android APIs do not operate directly with filenames, but 
+instead operate on resource IDs.  When you compile an Android application that uses resources, 
+the build system will package the resources for distribution and generate a class called "R" 
+(this is an Android convention) that contains the tokens for each one of the resources 
+included. For example, for the above Resources layout, this is what the R class would expose:
+
+public class R {
+    public class drawable {
+        public const int icon = 0x123;
+    }
+
+    public class layout {
+        public const int main = 0x456;
+    }
+
+    public class strings {
+        public const int first_string = 0xabc;
+        public const int second_string = 0xbcd;
+    }
+}
+
+You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main 
+to reference the layout/main.axml file, or R.strings.first_string to reference the first 
+string in the dictionary file values/strings.xml.
