ATL Server ISAPI DLL COM registration

Jan 8, 2010 at 8:30 PM

Does anyone know in what cases the ISAPI dll needs to be registered as a COM server (regsvr32)? I created with 2005 two projects. One just a basic web service. The default code created by the wizard does not have any com registrations.

Then I created another project as basic as the first one but I added the default perf counters. In this case the generated code specify that the ISAPI dll should be registered.

So when does the ISAPI dll must be registered?
