Invoking GetDotNetHost task from desktop msbuild fails

[pranavkm]

We use the GetDotNetHost task to discover the muxer path when being published from CoreCLR. However invoking this task does not work in desktop MSBuild.

 The "GetDotNetHost" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.
