.NET SDK 2.1 introduces a problem when depending on packages that contain build tasks built with pre-VS2017 tooling.
This is a work-around which excludes the problematic tasks in legacy targets that are depending on older version of the support libraries.
See dotnet/msbuild#2111
I don't understand why this has only become an issue with the update to .NET SDK v2.1 from v2.0
