Are you going to use Managed C++ ?

Managed C++ is not supported by .NET Compact Framework interoperability.
There is a very very poor support for COM technology but it is
possible with some effort.

So, the only simple way to use unmanagedo C++ (even codes written using
ATL classes) in .NET CF is P/Invoke. It is rather simple and structural
way (function calls from DLL) with no advanced OOP techniques.

You can use ATL, but not managed C++.

BTW, I can not uderstand why Microsoft did not
implement managed c++ support for .NET CF.
It would be very very useful for creating
common C++ classes wrapper for .NET CF in managed
C++ or even for COM/ActiveX wrappers.

I know that COM/ActiveX is not supported, but
wrapping it using P/Invoke is a big problem.
I think that there are peoples who would like to
develop some small wrappers for their solutions
and they don't want to use very very expansive Odyssey
COM/ActiveX wrappers.

Please consider, there is a lot of working COM/ActiveX
codes and witho
That's only my opinion.

Agreed, it would make P/Invoking much simpler. I think it was omitted
simply because of the required testing effort.

May be, but I would pay much for managed C++ and
COM/ActiveX (even simple implementation) support
provided by .NET CF.

There is a lot of COM/ActiveX codes and I don't think
that it is good to force people to rewrite it to .NET CF.
Reasons ?
There is still many many solutions and subjects for which
.NET CF is too slow and performance is not acceptable.
i.e. GIS/mapping applications, games, graphics, etc.

But I agree .NET CF is great solution for programmers
who want to develop something quickly i.e. prototypes.

It is my own opinion. Second one ;-)

CF v 2.0 will have COM interop, but still no managed C++, so they are not
necessarily linked.

do you mean CF v 2.0 will support a wrraper for those COM component developed with EVC before
then, i'll be able to use COM component within a C# project, right

thanks for a lot of msg

Yes. CF v 2.0 will have a COM class wizard that generates the interop
libraries very much like the desktop works now. You generate the interop
classes, then reference them from your code.

That's great information.
Thanks a lot.

All the best
