I downloaded the .NET SDK two months ago in the two setups:

(1) dotnetfx.exe - The 23 MB framework
(2) setup.exe - the 106 MB SDK

I also registered the path C:\WINNT\Microsoft.NET\Framework under the environment variables section. Yet I am not able to run the c sharp compiler from the command line. Although I am using Sharp Develop as well and that works just fine, but I wish to be able to compile raw code from the command line switches, just for pleasure. I also ran the batch file sdkvars.bat that comes with the SDK. Am I missing something?
