setup-dotnet

This action sets up a dotnet core cli environment for use in actions by:

• optionally downloading and caching a version of dotnet by SDK version and adding to PATH
• registering problem matchers for error output
• setting up authentication to private package sources like GitHub Packages

Please Note: GitHub hosted runners have some versions of the .NET SDK preinstalled. Installed versions are subject to change. Please refer to the documentation software installed on github hosted runners for .NET SDK versions that are currently available.
