an MFC-DLL using a namespace declared in a C# application

[pieter.gevers]

hi

I have a C# application (test.cs) that looks as like:

using System;

namespace CM
{ public class CallbackHandler()
{
}

public void PrintAttention(string out)
{ // print out out
}
}

Now I want to call the function PrintAttention(string out) from within
a function in an MFC-DLL.
How can I adress the function PrintAttention(string out) from the
MFC-DLL (unmanaged code C++).
I tried

#using "test.cs"
using namespace CM;

void function_in_MFC_DLL()
{ Callbackhandler test = new CallbackHandler();
test.PrintAttention();
}

When I write this I get a compiler error C2871 CM: a namespace with
this name does not exist

Can someone please give me advise or tell me what I'm doing wrong??

Thx in advance

change the compile option to add managed code support, and add the C#
assembly to project references

your

#using "test.cs"

should be

#using "test.dll"
