GetBuildVersion task fails for full Framework builds

Repro steps

• Create a new Console Application (.NET Framework)
• Install package Nerdbank.GitVersionong (either using packages.config or <PackageReference/>)
• Build the project

Error:

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.

I tested this using both Visual Studio 2015 and 2017 (15.8.1) on both Windows 7 and Windows 10 machines.

I do not know if it is relevant, but the Console Application is targeting .NET 4.6.1

@AArnott I’ve been out of town, so I haven’t had a chance to take a look at it this yet. At this point it might be Tuesday before I’ll be able to. Wanted to let you know that it’s on my radar.

I’ll be so happy once we get rid of all the problematic native dependencies and fix this once and for all!

FYI LibGit2Sharp 0.26.0-preview-0062 is up on nuget.org and it includes a separate ubuntu.18.04-x64 binary.
