Windows Phone simulator (emulator) automatically exits when a program is loaded.

Today, I am working on a Windows Phone.Program. After some refactoring, it was suddenly found that when you press F5 to debug the program, the simulator can start and load the program, but it just flashed, and then the program quickly exited. There is no error message or log file. Setting breakpoints anywhere in the program cannot be interrupted. I am really wondering.

 

After checking, it turns out that the problem was caused by modifying the namespace. After modifying the namespace, the startup object option becomes empty. It's no wonder that it's just a flash and it's gone.

 

 

Select a "startup object" to solve the problem.
