WP7 App Crashes Immediately upon deploy

Okay, so I'm developing an app for Windows Phone, and I can't seem to figure out what this issue is.

To start with, I should say my application compiles with no warnings, no errors, nada. Looks like a charm.

However, when I build the application to either the emulator, or any one of the two different WP7 devices I have on hand, the splash screen shows for a split second, and I'm returned to the home screen of the device.

Looking at the output:

'taskhost.exe' (Managed): Loaded 'mscorlib.dll'
'taskhost.exe' (Managed): Loaded 'System.Windows.RuntimeHost.dll'
'taskhost.exe' (Managed): Loaded 'System.dll'
'taskhost.exe' (Managed): Loaded 'System.Windows.dll'
'taskhost.exe' (Managed): Loaded 'System.Core.dll'
'taskhost.exe' (Managed): Loaded 'System.Xml.dll'
'taskhost.exe' (Managed): Loaded '\Applications\Install\6D7C6AA5-7D7C-4056-8BF7-1097F7FBAC40\Install\Subsplash.ExampleLibrary.dll', Symbols loaded.

'taskhost.exe' (Managed): Loaded 'Microsoft.Phone.dll'
'taskhost.exe' (Managed): Loaded 'Microsoft.Phone.Interop.dll'
The thread '<No Name>' (0xda1003e) has exited with code 0 (0x0).
The thread '<No Name>' (0xd660032) has exited with code 0 (0x0).
The program '[206110770] taskhost.exe: Managed' has exited with code 0 (0x0).

I'm guessing that it may be an issue with the dev environment. One more detail is that a few versions ago this was working 100%, then I changed some namespaces and folder names, and since then this issue has prevented us from doing any kind of dev. However, I'm confused as to why there would be a problem related to namespace name changing and folder change, but no build errors.

Thoughts?

If you've done any namespace renaming (especially of the App object) double check the startup object in the project is set correctly.

Try running Clean on the project.

Check the Startup object is set correctly in the project properties.

Check the DefaultTask in "WMAppManifest.xml" is pointing to the right view.
