Hi all, I have a "Managed Extensions" assembly written in VC++ (Visual Studio 2003 - VS7) that so far was build for .Net framework 1.1 customers. Since all the other assemblies developers in my project already moved to Visual Studio 2005 (VS8) with .Net framework 2.0 , and they want to reference my assembly as "project reference", I have to upgrade the prj file for Visual Studio 2005. On the other hand, I need that my assembly will be able to be referenced as "dll reference" for VS7 developers, and will be able to run for .Net framework 1.1 customers. In the following URL I found the answer for regular (c#) assemblies: http://weblogs.asp.net/israelio/archive/2005/06/08/410811.aspx Any ideas? Thanks a lot! Adi

Hi Christian, Thanks for your answer, but it seems to be that i have to make clear few things: I want that my unmanaged code (product written in c++) will be able to get a pointer to managed function (supplied by the .net customer) and activate it. Do u think it is possible? any ideas? Thanks again! Adi

thanks Prady, but... unfortunately, i can not iclude the callback functions as members of the c# wrapper, because those are external functions writen by users of the product. any other ideas?

hi everybody, i am wrapping some services written in c++ for .Net customers. because of performance reasons, i chose to do it was to write for each routine in c++ a analogous routine in c#, and do the same for all my own types. here is the problem: i have routine in c++ which one of its parameters is function pointer, and i would to give the C# user the ability to send a delegate that will take place exactly as the C++ user uses is own function. i was looking for solution all over the net with good enough answer for me. i also understand that normally there is no function pointer in c#. the question again in few words: how can i wrap c++ function pointer parameter by equivalent C# parameter? thanks in advance. adi
