Is there a free way to develop applications for my Galaxy Tab (Androind 2.2) using C #? Or are there only paid solutions?
Just evolve in Java with Eclipse. It's easy to learn, download and use for free (especially if you already know how to develop in C # with M $ tools), and there is a lot of community support.
MonoDroid is currently the only version of the CLR on Droid platforms, so the short answer is no. The cheapest solution is to get a student’s graduation from the MonoDroid store.
