PackageReference warning on Microsoft.NETCore.UniversalWindowsPlatform

[marcominerva]

With the latest version of the Plugin Template (5.2.0), there is a compilation warning:

A PackageReference for 'Microsoft.NETCore.UniversalWindowsPlatform' was included in your project. This package is implicitly referenced by the .NET SDK and you do not typically need to reference it from your project.

So the following line:

<PackageReference Include="Microsoft.NETCore.UniversalWindowsPlatform" Version="6.1.5" />

Should be removed from the CSPROJ file.

interesting.... is this not needed anymore?

What about for essentials? https://github.com/xamarin/Essentials/blob/master/Xamarin.Essentials/Xamarin.Essentials.csproj#L71

I will update this next week as I had some github issues yesterday and couldn't push code.

It depends on @onovotny's MSBuild.Sdk.Extras (used as Project Sdk): https://github.com/onovotny/MSBuildSdkExtras/blob/master/Source/MSBuild.Sdk.Extras/DefaultItems/ImplicitPackages.targets#L22

This doesn't happen with Xamarin.Essentials as it uses Microsoft.NET.Sdk as Project Sdk.

As an SDK reference, we can add additional nuget package references from there; that's not possible when used as a package reference. That's one reason for the difference.

Another is that the UWP reference should be defined as private and not included as a dependency on the generated nuget. The set of reference assemblies in there from a library perspective doesn't change; what does change are the .NET Native compiler bits. That's only relevant to apps. This helps prevent pain of package compatibility warnings too.

Ahhhhhhh i see, very interesting! Makes sense. I didn't realize it added it for me automatically.

Hi @jamesmontemagno! Any updates on this? :-)

[jamesmontemagno]

Yup, just setting up a CI cycle on this... wonder if i can ship directly to the marketplace or not
