Hi Folks,

I am just trying to port my Application from .NET 1.1 to 2.0.

Native C++ Code works fine.
Native C# Code also works fine (just some deprecations).

The problems start when trying to port my managed C++ Wrappers.

In .NET 1.1 with a lot of reading (mostly newsgroups like this) I managed to
create managed C++ DLL`s wrapping my native libs. The key problems where
these:

(In Linker settings)

1.) Additional Dependencies: mscoree.lib msvcrt.lib (or msvcrtd.lib for
debug version) mystaticlib.lib

2.) Ignore Specific Library: nochkclr.obj

3.) Force Symbol Reference: ***@12

This works fine and I would like to port this to the new CLR.

In Visual Studio 2005 i.e. .NET 2.0 I get the following Linker errors:

Could anyone please tell me how to solve these errors or where to find
newsgroups / tutorials for .NET 2.0 Interop? The usual suspects don´t know
about these issues (yet).

Thanks in advance for your efforts

Remove the /Zl option. Project Settings / C/C++ / Command line options .

I found that you first had to change `treate wchar_t as Built-in Type` to `No` (Project Settings / C/C++ / Language), click apply, then go to Project Settings / C/C++ / Command Line and remove the /ZI option
