An object that derives from DynamicObject in C# can have conditionals in its TryInvoke override, so it can change which method calls it responds to. However this sacrifices useful static compile-time checks, so it only gets used in unusual situations where the extra dynamic behaviour outweighs the cost. > whose results are then relied upon to be visible directly after invokation I'm not sure I buy that, surely those details are down to the individual methods in question. There's lots of hairy (distributed) COM code out there that doesn't make that promise for example, and it won't hold in a multi-threaded environment for objects that are not explicitly thread-safe in any case.
