Requirements
- Visual Studio 2022 (17.14+)
- .NET 8 or later runtime (10 recommended; the extension uses RollForward so 8 / 9 / 10 all work)
- .NET 10 SDK (only for local development/build)
- EF Core project
Local Build
The VS extension is strong-named with build/sgKey.snk (required for local/CI VSIX builds). The in-proc host uses wire DTOs under Host/Contracts/ and does not reference EFQueryLens.Lsp.Protocol; the LSP server bundle under server/ still includes Protocol for the out-of-proc process.
dotnet clean src/Plugins/ef-querylens-visualstudio/EFQueryLens.VisualStudio/EFQueryLens.VisualStudio.csproj
dotnet build src/Plugins/ef-querylens-visualstudio/EFQueryLens.VisualStudio/EFQueryLens.VisualStudio.csproj -c Debug
For F5 debugging, use Debug → Reset the Visual Studio Experimental Instance after large host changes so stale extension files are not reused.
