Hi There - I've built a custom module and have realized after packaging everything up that I am not sure which version of hte DNN assembly I should use. I developed against a custom build of the Core DNN, so now I have a higher version number. I replaced the assembly with a reference to 4.5, but then realized that some of the features I was wanting to use needed 4.6. So, then I used 4.6 and had problems with PortalModuleBase.. So, now, I'm wondering which version I should use to include as many users as possible, but more importantly, how to avoid this in the future? Should I always try to develop with a much lower version?Also, at this point, is it worth trying to accomodate 4.5, 4.6 or 4.7...there were problems with 4.6/4.7 and deprecated features from 4.5, right? Any insight in this area would be GREATLY appreciated!!! Thanks mucho!
