Description eb1 2012-05-23 09:14:07 UTC
When the args array contains a COM object implemented in unmanaged code then reflection doesn't find the c'tor to create an instance of the class although the COM object implements the interface requested by the c'tor.

It works if the COM object can be converted to a managed class.

This works in mono 4.0.0 and earlier, but got broken in master by 5d26590e79da139a284459299aee95c25f4cd835 which replaced the mono Binder class with the one from the ms reference sources.
