.NET Core Compatibility

[qmfrederik]

This PR adds some additional changes to make the project compile & the tests run on .NET Core.

Here's what I have

git checkout -- . git clean -xfd . .paket\paket.bootstrapper.exe .paket\paket.exe install dotnet restore cd tests\CommandLine.Tests\ dotnet build dotnet test 

which results in:

=== TEST EXECUTION SUMMARY === CommandLine.Tests Total: 274, Errors: 0, Failed: 0, Skipped: 0, Time: 1.409s SUMMARY: Total: 1 targets, Passed: 1, Failed: 0. 

Let me know if this work for you (& if this can be merged to master & we can have a NuGet release which includes support for .NET Core :))

Hey do you know how to make dotnet restore use the local project as a dependency instead of trying NuGet? When it attempts to restore CommandLine.Tests/project.json it fails because:

Unable to resolve 'CommandLine (>= 2.0.275)' for '.NETCoreApp,Version=v1.0' 

Which is obvious, since CommandLine for .net core isn't uploaded to NuGet yet :)

P.S. I'm trying this on Linux, maybe that's an issue.

@nemec You can use -f [path to CommandLine/bin/Debug] for that.

Normally dotnet restore should be able to find your other projects based on your global.json configuration, but somehow didn't quite get that working.
