[Xamarin.Android] 'obj\Release\monoandroid81\Resource.Designer.cs' could not be found

[xen2]

Started to happen once I updated VS2019 from 16.1.6 to 16.2.0

Seems to be due to https://github.com/onovotny/MSBuildSdkExtras/blob/master/Source/MSBuild.Sdk.Extras/Build/Platforms/Xamarin/Xamarin.Android.targets#L11
(until line 18).

Maybe those parameters are interpreted differently in latest Xamarin Android.

Note: this is a big blocker, can't compile anything without ugly workaround to remove the Compile from line 18.

Quick guess (since I don't have the old version anymore):
maybe it used to generate empty file before if there was nothing to write, but maybe in latest Xamarin.SDK it doesn't generate the file at all anymore?

This might be the actual change:
dotnet/android@ea6853a#diff-d07d3a1d454b339218b793dedae96995

[xen2]

Quick workaround:

  <Target Name="_RemoveNonExistingResgenFile" BeforeTargets="CoreCompile" Condition="'$(_SdkSetAndroidResgenFile)' == 'true' And '$(AndroidResgenFile)' != '' And !Exists('$(AndroidResgenFile)')">
    <ItemGroup>
      <Compile Remove="$(AndroidResgenFile)"/>
    </ItemGroup>
  </Target>

I can't seem to repro this in 16.3 preview 1. Does it repro for you there? If so, can you attach a small repro project? In my test library project, I see a Resource.Designer.cs in the obj\MonoAndroid81 directory.

@xen2 Could fix to 1.6 branch too, because I'm stuck with this version because UWP support.

Getting this too, thanks for the workaround @xen2

#174 (comment) fixed our issue. We added it to every project that targeted MonoAndroid

I had an odd dependency on the new billing library and it has a dependency on annotations. I had to add the resgen fix and turn off designtime builds too: jamesmontemagno/InAppBillingPlugin@1220af4

[clairernovotny]

I'm still unable to repro this locally....

I added @jamesmontemagno's files and it builds https://github.com/onovotny/MSBuildSdkExtras/blob/repro-attempt-for-designer/Tests/ClasslibWithNuGetSdkRef/ClasslibWithNuGetSdkRef.csproj

Can you try Extras 2.0.41? Should have a fix for this.
