Merge Risk: 🔵 Low · up to 48e54

The .NET Framework template still generates projects pinned to Polyfill 11.4.0, so they miss the 11.4.1 ReadAllLines fix. This is a narrow, localized gap; merge is reasonable with awareness of it.

Update the .NET Framework template pin.

src/TUnit.Templates/content/TUnit/TestProject.csproj disables automatic Polyfill injection for .NET Framework and still pins Polyfill to 11.4.0. Projects generated from that template therefore miss this update and the ReadAllLines fix. Update the template’s explicit package reference too. (github.com)
