Emulator Debugging Relaunch Not Reliable - nothingmn/AGENT.Contrib GitHub Wiki

The only time that I see this reliably happen is when you have too many resources included - that is, your app is too large to fit into the emulator's memory. Are you doing anything crazy/special? Lots of images/fonts/etc...?

Sometimes you'll get the blank screen if there is an error in your code, or that you have forgotten to send the updated Bitmap to the emulator using the .Flush() method.
