## Current Status

❌ **Cannot build yet - .NET 11 SDK required**

Your current SDK version: **10.0.103**
Required SDK version: **11.0.x** or higher

## Next Steps

### Option A: Install .NET 11 SDK (Recommended)

1. Download from: https://dotnet.microsoft.com/download/dotnet/11.0
2. Install the SDK
3. Verify installation: `dotnet --version`
4. Restore packages: `dotnet restore Jellyfin.sln`
5. Build: `dotnet build Jellyfin.sln`

### Option B: Rollback to .NET 10

Run the rollback script to revert all changes:
```powershell
.\rollback-to-net10.ps1
```

## Benefits of .NET 11

1. ✅ **No more Npgsql version conflicts!**
   - Npgsql 11.0.0-preview.1 is designed for .NET 11
   - Proper Entity Framework Core 11 support

2. 🚀 **Performance improvements**
   - Better JIT compilation
   - Enhanced garbage collection

3. 📦 **Latest features**
   - New C# 13 features
   - Updated BCL APIs

## PostgreSQL Provider Benefits

With .NET 11, the PostgreSQL provider now:
- ✅ Has proper version alignment with EF Core
- ✅ No longer needs version constraint workarounds
- ✅ Uses preview packages that are stable for .NET 11

## Testing Checklist (After Installing .NET 11 SDK)

- [ ] Restore packages: `dotnet restore Jellyfin.sln`
- [ ] Build solution: `dotnet build Jellyfin.sln`
- [ ] Run tests: `dotnet test Jellyfin.sln`
- [ ] Test PostgreSQL provider specifically
- [ ] Test SQLite provider (ensure compatibility)
- [ ] Run Jellyfin server and verify functionality

## Rollback Procedure

If you need to rollback to .NET 10:

1. Run the rollback script
2. Restore packages: `dotnet restore Jellyfin.sln`
3. Build: `dotnet build Jellyfin.sln`

## Notes

- The PostgreSQL provider will work much better on .NET 11
- All changes are committed to your Git repository (pgsql_conversion branch)
- No code changes needed - only framework version updates
- Third-party packages (SkiaSharp, etc.) remain unchanged as they're multi-targeted
