Invalid application object code was found. Recompile all objects.

I just got this error:

Invalid application object code was found. Recompile all objects.

From Microsoft Dynamics NAV 2016 (CU8) – As a response to a soap web service call. Gonna try the suggestion. At this point, I have no idea what the error is about. But Google did not supply any useful results, so I post this for Google to pick up.
