-- Blazor-based ASP.NET Core application
+## Modernization Summary
+
+### What Was Accomplished
+1. **Framework Upgrade**: Both projects successfully migrated from .NET 5.0 to .NET 9.0
+2. **Package Updates**: All critical NuGet packages updated to latest compatible versions
+3. **Security Fixes**: SkiaSharp CVE vulnerability fixed with upgrade to 3.119.1
+4. **Deprecated Dependencies**: Removed Application Insights (2.16.0) which was deprecated
+5. **Local Credential Encryption**: Implemented ASP.NET Core Data Protection API for secure credential storage
+6. **Backward Compatibility**: Existing plaintext credentials continue to work
+
+### Files Modified
+- Marechai.Database/Marechai.Database.csproj
+- Marechai/Marechai.csproj
+- Marechai/Startup.cs
+- Marechai/Pages/_Host.cshtml
+
+### Files Created
+- Marechai/Helpers/CredentialEncryptor.cs
+- Marechai/Helpers/ConnectionStringManager.cs
+- Marechai/CREDENTIAL_ENCRYPTION_GUIDE.md
+- .appmod/.migration/plan.md
+- .appmod/.migration/progress.md
+
+## Build Status
+✅ **Build Successful** - No compilation errors
+
+## Architecture Notes
+- All credential encryption is LOCAL-ONLY using Data Protection API (DPAPI)
+- No cloud services or Azure dependencies required
+- MariaDB database remains local and unchanged
+- Backward compatible with existing configurations
+- Graceful fallback from encrypted to plaintext credentials
+
+## Next Steps
+1. Test the application with existing MariaDB connection
+2. Deploy to production environment
+3. (Optional) Encrypt connection strings in production using the provided guide
