Tasks for practice in C#, where to find?

Question

C++ / C#

Good day, I write in C #, I want to raise my level of language proficiency in practice, what would you advise?

Answer 1

C# is a language, it is used in several areas - web (asp), windows (wpf), games (unity3d), etc.
What exactly do you want to pull up, what exactly do you write and use?
Decide whether you want to study or improve one of the areas, or delve into the language itself?
here is an example for the language: problembook.net
you can also read about clean code - regardless of the language, it will not be superfluous

Answer 2

hmm...
try to write your own control for wpf which thread
play around with nhibernate and entity framework

Answer 3

codewars.com - it's true that these are all problems of the algorithm level, but the language is also dragging along.
