Limited Travis-CI Verification

Because the verification system uses the linux-only Travis-CI service, verifying Windows-only tests has to be done manually and is very time consuming.

Consider including an additional test, likely based on Mono and FastCGI (e.g. xsp), that can run on Linux when submitting a new framework. This will drastically speed up our ability to merge in your pull request.

Different Mono Versions

While we have not currently run into the need to have multiple simultaneous Mono installations, it is possible

Debugging Mono + NuGet

Mono understands an environment variable MONO_LOG_LEVEL=debug that is helpful for checking that mono is properly working e.g. loading necessary DLL's.

Most NuGet commands understand a -Verbosity flag, which is great because the error messages can be completely mystifying when working with Mono too. Use this would enable all the debugging you can:

$ MONO_LOG_LEVEL=debug mono NuGet2.exe update -Verbosity "detailed" -self

For example, aspnet was constantly failing with this message:

Could not connect to the feed specified at 'https://www.nuget.org/api/v2/'. Please verify that the package source (located in the Package Manager Settings) is valid and ensure your network connectivity.`. 

Using -Verbosity "detailed" shows that the real error is actually a Mono library problem, as so:

System.InvalidOperationException: Could not connect to the feed specified at 'https://www.nuget.org/api/v2/'. Please verify that the package source (located in the Package Manager Settings) is valid and ensure your network connectivity. ---> System.Net.WebException: libMonoPosixHelper.so ---> System.DllNotFoundException: libMonoPosixHelper.so
