Fixing the MDT Integration for ConfigMgr 2403

For those of you that upgraded to ConfigMgr 2403, you may have noticed that some console extensions, like the MDT extensions, will cause the ConfigMgr console to crash.

Credits: Thank you Ahmed Essam at Dell for sharing your findings with the community!


When trying use any of the MDT console extensions, you get an an application crash, and the console closes. In the Application event log you will see errors with event IDs 1, 1026 and 1000.

Part of the Event ID 1 Error

That seems really silly — changing the XML namespace will break every console extension. But at least it's not hard to fix.
