partial trust, permcalc, and caspol, OH MY!

System.Security.SecurityExceptions will always be … well some kind of security problem ;)

Running .net exes over the network requires different .net perms. You can see the perms an assembly requires using permcalc from the .net sdk. It used to be called… I think permview.

You can run caspol –rs[g/p] %path to assembly% to see some info on the permissions. G will show you the groups it belongs to in the gac, P will list the permissions.
