Hi,

I have some C++ native clients that need to interact with managed assemblies
for which there are existing idl files (these assemblies are migrations from
C++ to C#).
The C++ clients use idl files to build the .tlh and tli files so they can
interact via COM with the assemblies.
Using #import  is unnecessarily large since only one interface is desired.
Also, the interface desired will not change whereas the assembly will thus
producing unnecessary dependencies which will force my C++ clients to
recompile each time the assemblies change even though the interface used by
the clients will never change.

This has prompted me with the question as to if it is possible to generate a
subset of the .tlb, which only includes the desired interface and which is
not sensitive to changes to the assemblies that implemented the interface.
