MonoGame Succinctly

An introduction to MonoGame development for C# developers.
This book is intended for people interested in game development using C# as your language of choice who want to target multiple platforms, including PC, iOS, Android, MacOS, Linux, PS4, PSVita, Xbox One, and Switch. Since this e-book is only a quick intro to the core information needed to get started, previous experience using C# is ideal, and almost required if you have no experience with another programming language.
If you have previous experience with Microsoft’s XNA technology, you’ll be very comfortable with MonoGame, and can probably skip most of this book.
