Application work in processes without startup - WPF

Question

I have a WPF application which has a daily restart timer, after daily restarting the application doesn't open, it is only appear in processes (taskbar for Win7) but not applications bar. There is no logged exception, also I logged a string in the beginning of startup function but also not logged.
