First pass at adding allowed System.* members to TypeLibrary Update MemberAccess test for system types Fix TypeLibrary.GetType<T>() It could return a random type that extended T, instead of T itself. Fix asking AccessControl about MemberInfos Fix TypeLibrary tests that assume a new library has no types in it Better fix for TypeLibrary tests Fix possible NRE in TypeLibrary.GetType( Type ) Simplify TypeLoader now that System types are in TypeLibrary Tweaked MemberAccess test again Double-check only public system members are included Log included system types in MemberAccess test Test for TypeDescription.Create<>() with forbidden constructors Don't allow TypeDescription.Create<T> for types with forbidden constructors
