Where can I find an open C# project to study other people's code?

Question

C++ / C#

I study programming from books, video tutorials and articles. They also advise reading someone else's code. Question - where can I read it? Advise on github. How to find good C# code on github or somewhere else for review? A combination of C# and WPF is desirable.
