How to embed Git and Gecko/Webkit in C#?

I need to embed Git and Gecko/WebKit in a C# application that should run cross-platform compliantly. Am I dreaming or is this开发者_如何学运维 possible to do without a lot of work?

I'm looking into Mono's WebBrowser support, but I'm wondering how often they update the Gecko/WebKit engine.

I'd also prefer to be able to embed Git. I could run Git commands via command line, but I'm afraid that C# limits me from having a Git implementation built-in.
