As a part of Visual Studio.NET it is the command line compiler for C# code. It is necesarry for program developers that makes programs coding in C#. It is only used on-demand when compiling a program or assembly, and should never run unexpectedly in background.

It's the C# (Pronounced "C Sharp") complier. It's an imporntant part of Windows and .NET Framework. It is not harmful.
  Daniel  
C# compiler, I don't know what it does compile though... In my case, it's running and I'm not compiling C# applications so it doesn't justify itself... I think it's safe though, because I haven't had a virus in a year now and I have a very stable and clean system.
