Hi, I don't think that a modified mscorlib assembly could ever run properly since the CLR use some "assumptions" concerning the layout of most primitive types like System.Object or System.String, valuetypes & enums, arrays...etc.
If you add a field to these types it would break these assumptions (especially concerning JIT compiler optimizations). --~--~---------~--~----~------------~-------~--~----~ -- mono-cecil -~----------~----~----~----~------~----~------~--~---
