Hello I'm just wondering what kind of practice do I need, because I'm ending with C++ and moving to c#. What do I need to be prepared most and what is the hardest part of learning C# from beggining
yours sincerely ! thanks :)

In short, forget everything you know about c++ and approach c# as a completely new language.

There is nothing hard about c#. It's childs play.

The hardest part of learning any language is forcing yourself to write logically in that language. It's pretty easy to write C++ in C# because there are many similarities, but that's not necessarily good C#.
