The Microsoft .NET Framework is a library of objects that create or draw things on the computer.

The C# language is used to create applications that display on a black window referred to as the DOS prompt or DOS window. Those are the types of applications we will learn to create in our lessons.

After clicking OK, a skeleton code would be created for you. Right now, we will not review what ever is part of the code. Everything will be introduced and explained as we move on.
