Have you tried debugging.. also have you tried googling how to open and close a splash screen using WPF.? or WinForms there are several working examples on `SO` as well http://stackoverflow.com/questions/48916/multi-threaded-splash-screen-in-c — MethodMan, Jan 25 '15 at 22:08
i try debugging and also searching on the net also youtube and i also found some similar case but it dont work in my case and i cant fix my problem. — forbiddenboy, Jan 25 '15 at 22:11
You don't have any code here that would close the "splash" window, so not much of a surprise that it doesn't close. There's nothing in the code you posted that would explain the `MainWindow` being shown more than once. I wouldn't implement a splash screen this way in the first place, but one thing that looks particularly wrong to me is that the call to `InitializeComponent()` really should be the _first_ thing in your constructor, not the last. Please fix your question so that it includes [a good, minimal, complete code example](http://stackoverflow.com/help/mcve) — Peter Duniho, Jan 26 '15 at 04:14
