So, I have a web part I wrote that is not working correctly, I get "object reference not set to an instance of an object." it works fine in dev, but when I installed in prod, it doesn't.
Anyway, if I replace the assembly in the GAC, does that cause any kind of iis reset, or app pools to recycle? Or do I need to reset anything for it to pick up the new assembly?
I only ask because I will not be allow to reset anything on the SP server during business hours, so I don't want to copy the new assembly if it will reset anything. In dev, I deploy using WSPBuilder, and I think that recycles the app pools when I click "Copy to GAC".
