Hello,
      Visual Studio generates the Interop.cwbx.dll file from some actual COM
library using tlbimp. Interop.cwbx.dll is a managed assembly providing the
required definitions of the types in your COM library. gmcs can compile your
app referencing this library because it requires no COM Interop to compile a
managed assembly. However, once you try to run your application you'll need
the COM support that exists in the mono runtime. 


Yes, you can write all the code contained in the Interop.cwbx.dll by hand if
you choose, just make sure to get it right or you'll get odd errors at
runtime.


Thanks,
Jonathan
