For any real development, the IDE is preferred. Microsoft offers a free version of Visual Studio Express , which has everything you need to get started with C #.
However, you can compile using only the command line compiler (csc.exe), which is included in the structure.
It must be located in the .NET installation directory; for example, on my machine for .NET 4, 64-bit, I have csc.exe in:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319
