I have an application that i have developed in .net 4.0 and on app startup i make a few database calls and bind my results to a couple different datagrids on different tabs in my main view. On my machine i get the results back in a couple seconds
and I can click on the various tabs and see my results in the various grids just fine. A couple users have updated to .net 4.5 and they are seeing some very bad performance suddenly. The initial database calls are taking more than a couple
seconds, they are taking a couple minutes. And after the db calls finish I bind my results to the grids but when they try click on another tab to view the different grids they are getting a not responding message and the entire app gets disabled
for a minute or two before the tab change gets processed. I myself am not firing off any code or any db calls on tab changes, all the data should have already been pulled back and bound to the various grids/controls on each tab. It's like
WPF and the notifypropertychanged stuff is the culprit and very laggy with the .net 4.5 update. If I try to reproduce on my machine it works great but I haven't updated to .net 4.5 yet. Anyone experienced this before or have any ideas as to what's
happening?
