Darn xml config file for a dll wouldn't load.

1) Searching Stackoverflow which says that only configs for exe files are loaded. Problem found and time to send bug report? Nah, better check source code first.

2) Downloading and reading the source for the dll. Nope, dll should explicitly load config file and read settings. Time to send problem report to author? Nah, better to test in greater isolation first.

3) Setting up isolated test. About to copy the LibName.dll.config.xml and WHAT? Note to self: You half witted twat, the file contents is XML, the bloody file extension isn't!

Now apply this sort of typo error to program code, and you will see why I use statically typed languages.
