The UnionCodeGroup class is a subclass of CodeGroup and is the most commonly used type of code group. Assemblies and application domains that qualify for membership are compared for membership against the children of the UnionCodeGroup, and so on down through the code group tree. The final permission set granted by the UnionCodeGroup is the union of its permission set, and the permissions granted by all child code groups of which the assembly or application domain is also a member.
