The result of a call to the Union method is a permission that includes all the operations represented by both the current permission and the specified permission. Any demand that passes either permission passes their union.
A GacIdentityPermission only supports set operations (the IsSubsetOf, Intersect, and Union methods) when the current permission is equal to the specified permission.
