Ah, same error here that I was seeing in #102:

  D:\a\Labs-Windows\Labs-Windows\platforms\CommunityToolkit.Labs.Skia.WPF\CommunityToolkit.Labs.Skia.WPF.csproj : error NU1701: Package 'SkiaSharp.Views.WPF 2.80.3' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETStandard,Version=v2.0'. This package may not be fully compatible with your project. [D:\a\Labs-Windows\Labs-Windows\Toolkit.Labs.All.sln]

@jeromelaban this looks similar to the issue posted here: unoplatform/uno#4036 - is this a regression maybe?

This is originally a warning that should be ignored. It's the SkiaSharp dependency which is usable for netcore, but is built on net47.

Thanks @jeromelaban, it does build and run fine locally. You said 'originally', so to clarify, should this be something we ignore or is it a concern that it's popped up again?

@michael-hawker I meant that its "origin" is in the SkiaSharp packages. You should be able to ignore the error by using <NoWarn> msbuild property.
