Hi everyone
I encountered this error when running unit test, after completing Service Update 10.0.39 (on dev environment), Build model, and sync database.
dashboard of D365 open still ok, no error , Service updated successfully.
I try to stop service SQL reporting, stop iis , refresh model, full build (with customn models), and sync database but it not work.
Message Error : Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '209'. Version of dll '208'.
Thanks for your help
