Description

I have an app that builds the metadata for a database and allows the BAs to define data elements. Some of the entities they deal with have up to 1000 attributes.

I have a Details screen where the user selects the entity from the list and can see the attributes for the entity in a grid. They don't like paging, but prefer to scroll through the entire list of attributes so I have turned paging off.

Yesterday I upgraded the app from Beta 2 to RTM version of LighSwitch and performance has slowed to an unacceptable level. Selecting an entity with 800 attributes takes several minutes for the data grid to fill. In the beta version, this would take 10-15 seconds to build the list.

The user system has 4 GB of memory so that should not be the problem, even though it runs a bit faster on my dev machine with 8GB.

Thanks for reporting this issue David. We attempted to reproduce the performance issue that you were seeing internally and were unable to do so.If you have any additional information that may help us to further narrow down the problem that would be appreciated.
