Should we remove the use of MSBuild.Sdk.Extras?

[brianlagunas]

If I remember correctly, the MSBuild.Sdk.Extras was used because at the time the Microsoft.NET.Sdk was lacking functionality. I do not believe that is the case today.

Is there any reason we should keep using the MSBuild.Sdk.Extras?

If not, I would recommend we drop the use of the MSBuild.Sdk.Extras and move to using the official Microsoft.NET.Sdk.

Thoughts?

Now that we no longer support .NET Core 3.1 and 5.0 we probably don't need this anymore.
