[Bug] .NET API bug - Nullable project throws error telling I should enable nullable about docfx

Weird, adding fetch-depth: 0 solved the problem, thank you very much. Feel free to close the issue if it's expected behavior

It seems following warnings are logged before CS8632 errors.

warning: [Failure] Msbuild failed when processing the file 'D:\a\ncalc\ncalc\src\NCalc\NCalc.csproj' with message: The "Nerdbank.GitVersioning.Tasks.GetBuildVersion" task failed unexpectedly.
Nerdbank.GitVersioning.GitException: Shallow clone lacks the objects required to calculate version height. Use full clones or clones with a history at least as deep as the last version height resetting change.

And by adding fetch-depth: 0 options to actions/checkout action. CS8632 errors seems resolved.

      - name: Checkout
        uses: actions/checkout@v3
        with:
          fetch-depth: 0

Another problem I've noticed is that the docfx metadata command returns -1 as an exit code.
But next line of script is executed.

It's because GitHub windows runner use pwsh as default shell.
And pwsh don't stop on native command error by default.
(It need to set PSNativeCommandUseErrorActionPreference = $true to change behaviors)

I also tried to using Linux before Windows and had the same error, except Linux completely broke my pipeline, Windows at least publish my articles
