Add .NET 12 support to all test project templates by Evangelink · Pull Request #56833 · dotnet/sdk

Evangelink · 2026-10-29T12:37:54Z

NUnit, xUnit, and Playwright-NUnit templates reject --framework net12.0, although the MSTest variants already support it. Add the missing framework choices so all 11 test project variants support .NET 12 without changing existing choices or net11.0 defaults.

Regenerate localized framework descriptions through the existing template build and add data-driven coverage that checks each generated TargetFramework without restoring packages.

Validation

Built the managed SDK layout and passed all 18 focused integration cases: 11 .NET 12 generation cases and seven existing .NET 11 cases.
Reproduced the seven baseline rejections and verified 33 updated generation outcomes across explicit net12.0, explicit net11.0, and default selection.
SDK build/test host: 12.0.100-alpha.1.26480.102. Source-template compatibility checks used 11.0.100-rc.3.26522.148.

Native AOT was disabled only for local validation because the C++ linker is unavailable. No build configuration files were changed.
