Develop Android app using C#

Question

Is it possible to write an android app using C#? Is there an API or something? Is it free for personal and commercial development?

What do I need to install to have

Answer 1

Here is a new one (Note: in Tech Preview stage): http://www.dot42.com

It is basically a Visual Studio add-in that lets you compile your C# code directly to DEX code. This means there is no run-time requirement such as Mono.
