Hi Folks,

I got a Wrapper Dll around a native C++ static library. In .NET 1.1 this
worked fine. When moving to .NET 2.0 I get a couple of unresolved externals /
linker errors:

Error    32    fatal error LNK1120: 9 unresolved externals    Debug\empDll.dll

In my .NET 1.1 Project I had to make the following Linker Settings to build
the DLL:

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: __DllMainCRTStartup@12

In my Wrapper Classes I had to add the following:

#using <mscorlib.dll>

using namespace System;
using namespace System::Runtime::InteropServices;

This does not work any longer with the new Visual Studio and the new .NET
Framework.

The only article that I was able to find on this subject:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnvs05/html/TransGuide.asp

DoesnÂ´t mention Linker settings at all.

Could anybody please help me or tell me where to go for further reading?
Thanks in Advance for your efforts.
