My app does not seem to be working on 256mb devices, and tracking down why is difficult!
On running the app, before the mainpage.xaml is even loaded I get an System.OutOfMemoryException in System.Windows.dll and then one in Microsoft.Phone.dll
The exception happens between finishing the App.xaml startup and Navigating to my mainpage.xaml
Is there anyway I can trap this? Or find out why its happening. Looking at the memory usage of my app at this stage its very low, around 10mb maybe, its hard to say on the graph, but certainly way below 90mb limit.
