Vista - PSSnapIn InstallUtil Problem -- "That assembly does not allow partially trusted callers.."

I'm trying to create my first PSSnapIn. However, I'm getting "That assembly
does not allow partially trusted callers.." when attempting an installutil
on the compiled DLL.

I'm going for the minimalist approach and not using Visual Studio to
generate "AssemblyInfo.cs" or csproj files. Is that what is messing me up?
Is there a way to use another editor to create the cmdlet and snapin CS
files then just compile and install them?

Please pardon my C# workflow ignorance.

Thanks,
Alan

An exception occurred during the Rollback phase of the installation. This
exception will be ignored and the rollback will continue. However, the
machine might not fully revert to its initial state after the rollback is
complete.

The Rollback phase completed successfully.

The transacted install has completed.
The installation failed, and the rollback has been performed.

Just to complete the loop, I found the following article on the PowerShell
Team Blog:

"The worlds easiest way to create/install MshSnapins"
http://blogs.msdn.com/powershell/arc...25/583258.aspx

With a few obvious changes the script works with Powershell and you don't
have to do the SnapIn code.
