I'm upgrading our codebase from B2 to RTW and I'm having a problem where Application_Exit is called from somewhere. I've setup breakpoints and stepped through as much as I can, but something is calling Application_Exit and I can't figure out where, or how to prevent it. I've got try/catch in my code as well as an Unhandled Exception setup, but nothing is getting caught.
Anyone have any advice for tracking this down?

Thats the path I'm currently going down. Its a reasonably big Silverlight app, so it takes a while to go control by control. I really wish there was a way to at least narrow down which control is calling Application_Exit.

My problem ended up being the data grid changes. Apparently if you are still using Header, it'll just go to Application_Exit without giving you an error message. Its not listed in the Breaking Changes document, but is here: http://blogs.msdn.com/scmorris/archive/2008/10/15/post-beta-2-breaking-changes.aspx
Original:
<dg:DataGridTextColumn.Header> <HyperlinkButton Content="Asset Type" Tag="AssetType" Click="Sort_Click" /> </dg:DataGridTextColumn.Header>
New:
<dg:DataGridTextColumn.HeaderStyle> <Style TargetType="Primitives:DataGridColumnHeader"> <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <HyperlinkButton Content="Asset Type" Tag="AssetType" Click="Sort_Click" /> </DataTemplate> </Setter.Value> </Setter> </Style> </dg:DataGridTextColumn.HeaderStyle>
