Missing Microsoft.ResourceManagement, Version=4.0.3531.2
I had a problem with User Profile synchronisation not working any more. The service would be stuck ‘starting’ and I could not access the service page of the User Profile Service any more. A little investigation pointed me to an assembly problem; it was searching for Microsoft.ResourceManagement version 4.0.3531.2. I had no idea why.
I did install the october 2010 cumulative update, which was a faulty one when it was first released. I don’t know if this had anything to with it, but changed were made to the user profile config file. To correct these, follow these steps:
- Open up Microsoft.ResourceManagement.Service.exe.config and go to the end of that file.
- In my case, there were some illegal assembly binding redirects in the config file, which forced the executable to search for version 4.0.3531.2 of the assemblies. Comment out those lines.
- Now restart the User Profile service and Sync service. This should work now.
- After restarting the services; don’t forget to run an iisreset on your box when it also hosts Central Administration.
After these steps, all was working fine again. I have not a valid clue on what caused this, but at least it’s solved now 🙂
