Continue working with C# and find some decent open source .NET projects to work on, like RestSharp (generic REST wrapper library) or BlogEngine.NET, or work with some of the .NET APIs you aren't familiar with yet. I'm in the process of teaching myself WPF (Windows Presentation Foundation) for making Silverlight web-apps and desktop apps and it's really quite fun; what's not to like about being able to hammer out a slick-looking desktop app in a matter of minutes? Plus with WPF you're forced to learn how to implement parallelism and event-driven programming which are both good experiences that have tremendous real-world value even if you don't end up taking a job some day where you need to use .NET or C#.
