- 30. What I needto use Xamarin? • Xamarin development can be done in either Xamarin Studio or Visual Studio. The IDE you choose will be determined by the platforms you wish to target. • Because Windows Phone apps can only be developed on Windows, it is impossible to develop for all three platforms on the same operating system.
