If you are building a Windows Phone 7 App, you should be aware that if your application uses more than 90MB of RAM it will get rejected from the marketplace. One easy way to check how much RAM your application is using is to add Peter Torr’s most excellent memory counter. It adds an additional counter to your app. You know, those counters…those funny little numbers on the right to your application when you run it in the debugger.
