Trouble exporting an unmanaged class from a class library

[ajerijian]

Hi all,

My apologies for posting this message into the wrong newsgroup. I'm
reposting it here since it's more appropriate.

I am attempting to export an unmanaged (__nogc) C++ class from a class
library into an C++ application compiled using the CLR. Within the
class library, I have declared the class as follows:

__nogc class __declspec(dllexport) CMyClass
{
....
}

I put in a conditional compile so that if an application includes the
header file, the class declaration is instead the following:

extern __nogc class __declspec(dllimport) CMyClass
{
....
}

This generates a LIB file that I can use to link the class library
against the application.

However, if I try to run the application from within the framework, I
get the following error:

Unhandled exception at 0x77f966bc in WrapperTestApp.exe: 0xC0000142:
DLL Initialization Failed.

I have copied the class library DLL and LIB files to both the project
folder and the Debug folder where the application executable is
located.

What could I be doing wrong?
