Why is LC Task not supported with .NET Core

[JanThomas118]

I am talking about the following Code snippet. https://github.com/dotnet/msbuild/blob/main/src/Tasks/LC.cs#L94-L107

This prevents handling of licx files for .net framework applications with dotnet build. Instead msbuild.exe must be used.
This is annoying because the UX of dotnet build is much nicer and in my measurements it is considerably faster. (Even if msbuild.exe /m is used)
I understand that lc.exe is obviously not supported on non-windows platforms and that there is no intention of porting it.
But this Task is just calling an external executable and should be able to run on .net-core on windows.

In my head the method would look something like this and the preprocessor directive would be removed:

	bool isWindows = System.Runtime.InteropServices.RuntimeInformation.IsOSPlatform(OSPlatform.Windows);
	if (isWindows)
		return base.Execute();
	Log.LogErrorWithCodeFromResources("TaskRequiresFrameworkFailure", nameof(LC));
	return false;

This Task is one of many that live in the MSBuild repo for mostly historical reasons. The MSBuild team doesn't have subject matter expertise over this Task and so we defer to the actual owners for timelines for updates and feature requests. Based on the issue linked in the XML comment - that is a very high bar. We're not going to expand support until/unless the actual owning team wants to add support.

Thank you. I am going to ask in the winforms repo where the linked issue was created aswell.
