Xamarin, the Mono company from Miguel De Icaza and others, publishes some nice Mono seminars. It's worth checking out; especially if you are interested in building c# apps for Mac OSX, Android, iOS, and linux. Oh, and you can use the same code to run on Windows or Windows Phone.
Also, some people have managed to get c# code running on Heroku, which is my favorite PaaS provider.
Update: If you haven't played with MonoDevelop and Mono in a while, you're missing out. It's becoming the realization of Java's promise of cross platform development except with out all the Java mess. Plus, Mono has better startup performance to match good overall performance. I was planning on Python and NodeJS as my next skill upgrades, but Mono is getting bumped ahead of those. It should be a fairly quick upgrade for any .Net dev.
