How to develop 2d games in C#?

Question

C++ / C#

What technology (framework) can be used to develop 2d games (in particular - top view) in C # on a PC (in the future - on Android)? XNA, as I understand it, has been killed, Unity3D is not very suitable for 2D games. Is it worth learning MonoGame, or is it better to try learning Unity, or are there any other options?
And where can I read about the specifics of using C # on these 2D frameworks?

Answer 1

Is Unity3D not very suitable for 2D games?
Suitable absolutely as well as for 3D games, because 2D is a special case of 3D!

Answer 2

Look at cocosSharp and monoGame
