In order to load the projects in Visual Studio, you need to specify a target framework. I think at the time I just picked the lowest one? The target framework shouldn't be used anywhere so it could probably be anything.

Thanks for the contribution!

Sorry, I should have elaborated. I meant the build target framework in this repository for the projects: <TargetFrameworks>net40;netstandard2.0</TargetFrameworks>.

Oh I think it so we can run tests against multiple frameworks. net40 and netstandard2.0 are the most compatible with runtime frameworks:
