Quick and dirty demo of the C# language support so far:

There are several issues still, but it's a start and demonstrates the work done so far on LSP support:

• Omnisharp can be slow to start, especially the first time because it downloads the binary package. #383 is planned to help smooth this over.
• There are several completion issues that seem more prevalent in C#, for example #376.

And there are still several pieces of the LSP to implement - #379 (syntax highlighting), #378 (signature help).

Additional out-of-the-box language support will soon be implemented for Python (#384), Rust (#385), and ReasonML (#389) for the 0.3 release.

Also, big thanks to @jordwalke for the generous contribution at our BountySource page. We'll be putting more bounties for issues in the 0.3/0.4 milestones.
