I have a server running the FIM 2010 Sync Engine only. It appears that the Microsoft.MetadirectoryServices DLL is not in the GAC on this machine. If I look on a server running the web service then I see this DLL in the GAC. This is a pretty big change from earlier versions. Was this change intentional? It seems that it becomes much more difficult to rev the DLL in the new world. A new DLL woul dneed to be copied to every folder where custom extensions are being developed. It also makes it more difficult for partners to develop third-party apps. We can no longer rely on having the DLL in the GAC. Does anyone have any more information on this? Thanks! -Jeremy

We don’t GAC Microsoft.MetadirectoryServicesEx.dll at all. Cheers, MarkusMarkus Vilcinskas, Knowledge Engineer, Microsoft Corporation

Can you confirm that it is NOT GAC'd on a server running the service and/or the portal. My earlier inviestigation showed that it was GAC'd on a portla server but was not GAC'd on a server where the Sync Engine was installed without the portal. -Jeremy

Yes. Cheers, MarkusMarkus Vilcinskas, Knowledge Engineer, Microsoft Corporation
