Is it possible to install a C# compiler without Visual Studio?

Question

I want to build projects from the command line. Is it possible to deploy a C# compiler without installing Visual Studio?

Answer 1

Contrary to what some of the other answerers say, you do NOT need the SDK, just the .NET Framework to get the C# compiler, csc.exe.

Also, consider other (free) IDEs like MonoDevelop, #develop, and Visual C# Express. (You said you don't want Visual Studio, not that you don't want an IDE at all ;) )
