Where is the .NET command line compiler?

Where is the .NET command line compiler (csc.exe) located after install?

I'm trying to set up my path to compile C# applications from the command line, but I can't find where csc.exe has been installed.

I'm using .NET 开发者_开发问答4 and Windows 7 Pro 64-bit.

In the respective %windir%\Microsoft.NET\Framework\vXXXX folder.

Each version of the runtime has its own compiler, which would make 4.0:

%windir%\Microsoft.NET\Framework\v4.0.30319\csc.exe

Your minor version (the 30319) may vary.
