ISAPI that use managed extension does not work under IIS6 ?

[Lionel Schiepers]

I rencently tested an web application with ISAPI extensions that internally
use managed extensions but the call to the ISAPI failed. I receive the
following message: "A dynamic link library (DLL) initialization routine
failed." in my browser. These ISAPI extension work when they execute under
W2K or WXP.

To reproduce the problem, I've create a simple isapi extension with visual
studio 2002 and visual studio 2003 and changed the code with:



At the top of the file

#if defined(_MANAGED)

#using "System.dll"

using namespace System;

#endif





Changed the implementation of Default(CHttpServerContext* pCtxt) to:

void Cisapi2002Extension:efault(CHttpServerContext* pCtxt)

{

StartContent(pCtxt);

WriteTitle(pCtxt);

*pCtxt << _T("ISAPI 2002<BR>");

#if defined(_MANAGED)

*pCtxt << _T("MANAGED<BR>");

String *s=String::Concat(S"", S"");

#else

*pCtxt << _T("NOT MANAGED<BR>");

#endif

EndContent(pCtxt);

}



The ISAPI works if the project is not compiled with Assembly support.

Is there any workaround to use ISAPI extensions that use internally .NET
under IIS6 ?

You might want to experiment on the web server to see if managed code runs
on that box outside of IIS.

In any event, it might be a good idea to post your question again here:

microsoft.public.platformsdk.internet.server.isapi-dev

Is there anybody at Microsoft ?

Thanks.

In case you haven't seen his post, David Wang replied that he is researching
the issue after your second post in the ISPAI group.
