Show wpf application on startup in taskbar without using System.Windows.Application

Question

Our application does not appear in the taskbar on startup, because it is a WPF window displayed over ShowDialog but not using System.Windows.Application . Is it possible to show the app in the taskbar?

var spl = new SplashScreen();  // Nothing in the taskbar, but it should...
spl.ShowDialog();

// initial application

spl.Close();

var app = new App();
app.Run(mainWindow);   // Now we have some thing in the taskbar

Thank you very much.

var sp1 = SplashScreen();    
sp1.ShowInTaskbar = true;
