What's Changed

Enhancements

• Pin actions to commit SHAs in workflows by @​priya-kinthali in actions/setup-dotnet#744
• Expand the CSC problem matcher to light up more errors on GitHub. by @​StephenCleary in actions/setup-dotnet#717
• Improve global.json SDK version validation for rollForward by @​priyagupta108 in actions/setup-dotnet#742

The action now validates the sdk.version field in global.json when rollForward is specified. The version must be a fully-qualified SDK version (e.g., 8.0.100, 10.0.100). Wildcard versions (e.g., 10.0.*) and runtime-style versions (e.g., 8.0.0) will now fail. See the .NET SDK version specification for details.
