true if o is a System.Security.Policy.GacMembershipCondition; otherwise, false.
There are no degrees of global assembly cache membership. An assembly is either in the cache or it is not. If the object identified by o is a System.Security.Policy.GacMembershipCondition, then the objects being compared are equal. This method returns false only if o is null or if o is not a System.Security.Policy.GacMembershipCondition.
