The first steps in the marina studio, still not even smelled mono and xna. I found a couple of lessons and each of them uses the Microsoft.Xna libraries. However, these libraries do not work for me in any way.
Xamarin studio installed according to the instructions https://developer.xamarin.com/guides/android/getting_started/installation/windows/manual_installation/#Installing_Java_SDK_((JDK) And GTK installed according to the same instruction. How to solve a problem?
