where do I find the ILDasm.exe in .net?

I'm reading a book on .net and it talks about using the ILDasm.exe to check out a manifest. Unfortunately, it doesn't say how to run ILDasm and I can't find it anywhere in the IDE. I'm running .net professional. Is it not in that version or is it somewhere else where I'm not looking? Thanks.

Just do a search for files on the ILDasm.exe and you'll see where it's located...
I just searched and found it at Microsoft Visual Studio .NET\FrameworkSDK\Bin
so yours should be somewhere there too..
