Hi all

Exiting COM ATL DLL wrapping a C++ library. Interoping from a C#
application, passing a large string containng XML (5-130kb). Need to
significantly improve performance of both the interoping and the
performance of the native functions (performance critical app).

Opinions sought on most worthwhile course of action...have identified 4
options...

1. Implement a managed C++ wrapper and link to underling C++ functions,
marshalling non-native types where necessary. Thus eliminating COM
(quick win?)
2. Re-write C++ code in C#. (no quick win, not possible to re-write all
of it also)
3. Recompile C++ code with VC7 or higher (currently VC6)...quick win?
4. Re-architect C++ code (no quick win)

Thanks all
