actions/setup-dotnet@v1 with dotnet-version fails very cryptically

[smithago]

I had a github workflow action like below

• name: Setup .NET Core
  uses: actions/setup-dotnet@v1
  with:
  dotnet-version: 3.0

You can try it, It kept failing cryptically with an error like

##[error]Node run failed with exit code 1

I could not figure out why it was failing, there was no info in the raw log either.

Finally after several trial and error, I figured it was related to version and I changed to version to 3.0.100 and it worked.

Please fix the error message to more actionable ones.

Thanks, this will be good to update. We are making changes to the way installation occurs and should verify this once #10 and #14 are addressed.

@ShubhamSureWash This action is for installing .NET Core. For the hosted runner you are using, 4.8 is installed on the agent. https://github.com/microsoft/azure-pipelines-image-generation/blob/releases/vs2019/20191202/images/win/Vs2019-Server2019-Readme.md#net-48

Any updates? 3.1.102 is out and this task fails to install it.

Error logs now include the message: Could not find/download: ".NET Core SDK" with version = 4.5
