Thanks Jason. That basically confirmed what I was thinking: the framework
('System.Windows.Forms') is the reason for the exception. The next
question, does anyone know of a way to union permissions in the attribute?
I noticed the 'StrongNameIdentityPermission' has a method to union
permissions but this is not available in
the 'StrongNameIdentityPermissionAttribute' class. I'm not sure it even
makes sense but am thinking that I would like to union my public key and
the framework's so this exception wouldn't be thrown. Does this make
sense? I'm just thinking out loud here but wouldn't it make sense to do
the demand all the way up the call stack or is the 'LinkDemand' sufficient
in everyone's mind? Better yet, can anyone think of a reason why I
wouldn't want to do this (grant permission to the framework)?
TIA,
Dave.
