Partial/Full Trust mode verification in Asp .Net 4.0

Question

I found the similar question on Msdn's forum but without answer (you can check it here) .Net 4.0 came with obsolete method

IsUnderHighTrust = SecurityManager.IsGranted( 
  new AspNetHostingPermission( AspNetHostingPermissionLevel.Unrestricted ) );

As a replacement it is suggested to use AppDomain.CurrentDomain.PermissionSet

var permission = new PermissionSet(PermissionState.None);
permission.AddPermission(
  new AspNetHostingPermission(AspNetHostingPermissionLevel.Unrestricted));

IsUnderHighTrust = permission.IsSubsetOf(AppDomain.CurrentDomain.PermissionSet); 

But PermissionSet is also requires Full trust mode.

So the obvious question - how to check under Asp .Net 4.0 if application is under Full or Medium Trust mode?

Answer 1

How about putting a try/catch around a block of code (like the PermissionSet check above) that requires full-trust and catch on a SecurityException? It's not as pretty because this isn't what a try/catch should normally be used for, but seems it would accomplish the goal none the less.
