How to fix set-output command is deprecated in Github Action

Running microsoft/setup-msbuild@v1.0.2 and Run NuGet/setup-nuget@v1.0.5 is now deprecated and you should upgrade the version. The underlying set-out is being removed from 1st June 2023. Instead of set-output the $GITHUB_OUTPUT should be used instead.

Warning: The `set-output` command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Your Github Action pipeline will look something like this

    - name: Setup MSBuild
      uses: microsoft/setup-msbuild@v1.0.2

    - name: Setup NuGet
      uses: NuGet/setup-nuget@v1.0.5

Solution to set-output

Update the version on setup-msbuild and/or setup-nuget

   - name: Setup MSBuild
      uses: microsoft/setup-msbuild@v1.1.3

    - name: Setup NuGet
      uses: NuGet/setup-nuget@v1.1.1

In details the set-output should be change from

- name: Set output
  run: echo "::set-output name={name}::{value}"

And use the $GITHUB_OUTPUT instead like this

- name: Set output
  run: echo "{name}={value}" >> $GITHUB_OUTPUT
