I recently was overhearing the conversation a colleague of mine was having about debugging a large Win Forms application. It seems he was jumping through some major hoops to be able to debug the application. Without getting too much into the architecture of the solution, it was instantiating other applications through a messaging system backend to communicate between apps. In order to debug it, the team was using some code workarounds to kill processes, muddle around with new threads and processes, create a new process in debug which then impersonates some other process etc. At least that’s what I think was happening.
There was a recent post on LessThanDot to create a small application to find all the "Friday the 13th's" occuring in a range of dates. Here is my simple solution to the challenge. I also made it flexible enought to find any occurrence of a day / day of week combination within that range. It runs surprisingly quick even when looking over the next 500 years.
