That's an explanation any developer dealing with end-users very likely have heard. In fact almost always it can be translated as "the stupid thing is not working; I have changed something that I'm not aware of; I cannot find yet a suitable person or entity to blame for; fix it fast because I'm already two days late with my report!".
Very nice, then today I am such an end-user. The data part of a .NET WinForm application throws an exception. One of the following postulates for sure must be false:
- "this morning everything worked"
- "I swear I did not change anything"
To make it short, in app.config I have created the appSettings section preceding the connectionStrings section. It is not my first visit into this little trap.
Once I remember I heard from a user that "we did not change anything really, just installed new Office version".
