.NET Standard 2.0 support

[tmct]

Hi Peter,

My team have used your library in a .NET Core application and so had to make a few changes to target .NET Standard 2.0. We're considering turning these changes into a PR back to your repo, but want to ensure we've not regressed behaviour on any supported platform.

Please could you let us know how you currently build and test the application for all targets (net45, net40, net20, mono)? Is there any form of CI? Knowing this would help us to perform adequate testing.

Thanks,
Tom

I've just spotted your appveyor build :) Should have spotted that before. Taking a look, thanks

Aren't long paths supported internally by .NET Standard 2.0?
