I was hoping to be announced for the development of a universal approach for all systems. Why do I need to know anything else other than C# and .Net, that would be to program for Android or for iOS? Why MS does not support Silverlight? Why MS does not understand how important it is for developers to write code once, that he would work everywhere? Without any problems, without any additional work and time. This problem is to be solved first. It is more important than Azure, or shop than on the phone. Much more important. Ask what want developers, you broke away from us. I love C #. I code on C# for 12 years. But now I have to go from C# and. Net. I want to write in C # anywhere from drivers to the markup in browsers, from windows to android, from web to desktop.
