Hot Swapping in Production

Hotswap ScreenshotA (repeat of) a word to the wise – with a twist, if you read to the end. One of our clients was getting CIL errors; I don’t have details. It was discovered (I cannot take credit) that the checkbox to “Allow hot swapping of assemblies when the server is running” (or on my version “Enable the hot-swapping of assemblies for each development session.”) on the server configuration was checked.

A reminder of what we read in Inside Microsoft Dynamics AX 2012:

“However, you should never do this in a production server because any breakpoints that are encountered will stop all of the managed code from running, essentially blocking any users who are logged on to the server and processes that are running.”

The book goes on to mention performance issues as well.

A coworker just pointed out, and this is the part that really gets me: The installation default is to have the checkbox set on.

Happy DAXing!
