That debug moment where you have 50+ different vs.net web projects in one solution and each of the said web projects were set up using point-and-click web references, then realised that the developer who created it did not even bother to let people know that you need to run it all simultaneously and did not bother to use host names but instead used the http://localhost:<some-random-port> in IIS express.

Oh, just to rub salt in the wound, each project's programming code files jumps from a mix of vb.net to c# which is a complete waste of time and energy to do.

Whoopdee do. The debug task from hell.
