Use Travis CI language support for .NET

[akoeplinger]

Travis CI now supports C#, F#, VB projects. It uses Mono internally, just like you did previously in your .travis.yml. I also added sudo: false, so builds get routed to the new container infrastructure.

I'm one of the contributors that worked on this for Travis, feel free to ask me any questions :)

Cool.

Just very unfortunate name "csharp" - why not "mono"?

[akoeplinger]

Yeah, we had a lengthy discussion about the name.

Using mono or dotnet didn't feel right, cause they are framework/runtimes and not languages (and all the other languages on Travis follow this same pattern, e.g. java and scala instead of jvm).

We contemplated about having separate csharp, fsharp and vb names, but the Mono package on OSX actually installs all of them anyway, so it wouldn't make a difference there and we didn't want to make it behave differently on Linux vs OSX. Another issue was that you can mix and match languages in an .sln, so how would you tell that you're using both C# and VB?

In the end we decided to just go with csharp and see what the feedback is :)

Would be awesome if you could check https://github.com/fsprojects/Paket and https://github.com/fsprojects/ProjectScaffold too. Thanks!
