How to enumerate running processes managed by CLR?

How to enumerate running processes? What about app domains?

Would there be any security-related gotchas?

I would be comfortable with .NET 4.0 only, Windows 7/Windows Server 2008 R2-only solution.

P.S.: This is what I am trying to do... ProcessExplorer.NET question

System.Diagnostics.Process.GetProcesses() will list all the running processes as Process objects.

Once you use Process.GetProcesses above, you can use ICLRMetaHost::EnumerateLoadedRuntimes to see if the process is running an instance of the CLR, and get the versions of the CLR running in it. http://msdn.microsoft.com/en-us/library/dd233119.aspx. The API isn't exposed to .NET directly, but it's COM so you can tlbimport mscoree.dll and use the autogenerated wrappers in .NET.
