Assembly

Hello,
I am trying to develop a simple shared assembly. For that, I have created a component. And want to generate a key file using "sn.exe" utility. I ran code like this
"sn -k mykeyfile.key"
in command prompt. But I am getting the following error in command prompt

“sn is not recognized as an internal or external command , operable program or batch file.”

I was able to find the sn.exe utility on my machine. But unable to run the file.
Can some one assist me what I am doing wrong

Thank you!

The program is not in the path. Go to the VS.NET command prompt and run it again.
