Hi,

Are there any problems with using CoRegisterClassObject/ROT in .NET/CLR to
expose an object as IDispatch for communication from/to unmanaged world? It
is registered from MTAThread. The DllImport is as follows:

[DllImport ("ole32.dll")]
static extern uint CoRegisterClassObject (ref Guid rclsid,
  [MarshalAs (UnmanagedType.IDispatch)]object pUnkn, ...);

I'm asking because .NET provides RegisterTypeForComClients() and it has the
following comment:
"This method, which is equivalent to calling CoRegisterClassObject in
COM...Using the RegisterTypeForComClients method can cause unpredictable
results, particularly if the application is multithreaded."

Could someone specify the "unpredictable results" referred to in the msdn
docs?

Thanks in advance
