notMarshalable managed debugging assistant (MDA) is activated when the common language runtime (CLR) encounters a COM interface pointer without a valid registered proxy/stub or an incorrect
IMarshal interface implementation while attempting to marshal the interface across contexts.
Calls are not serviced, or calls occur in the wrong context for COM interface pointers.
No valid registered proxy/stub or an incorrect
IMarshal while attempting to marshal the interface across contexts.
Make sure you have a proxy stub registered and that the
IMarshal implementation is valid.
This MDA has no effect on the runtime.
