Splash Screen

[Micaias-Bobadilla]

Hi, I'm trying to make a splash screen, and I started the project using version 3.0.5 of Lepoco (upgrading to 4.0.0 crashes some classes). What I do is put a window in the App.xaml.cs with the method OnStartup() like this:

private async void OnStartup(object sender, StartupEventArgs e)
{
    var splash = new SplashLoadingWindows();
    splash.Show();
    //Initialize a heavy-duty service such as connecting to the database
    await Task.Run(() =>
    {
        var dato = _host.Services.GetService<ISessionFactory>();
    });
    await _host.StartAsync();

    splash.Dispatcher.Invoke(() => splash.Close());
}

But I found it is kind ugly doing this way.
It work for me cuz the splash Screen is on while getting the service , it takes a while, like 3 or 1 seconds. Cuz it's a connection on the database.
And that is the goal, but I want to know is there a better way to do this

I'm not sure if it's any better, but this is how I did it. I created a Window called Splash.xaml, then show it on the Loaded event in the MainWindow by putting the following code in the MainWindow.xaml.cs constructor. My Splash screen then does a few things, including checking the database connection.
I just do that in the code behind (not strict MVVM but it works). When it's done the main window is maximized.

WindowState = WindowState.Minimized;
ShowInTaskbar = false;
Width = 0;
Height = 0;
WindowStyle = WindowStyle.None;
Loaded += async (sender, e) =>
{
    var splash = new Splash(queryService,  userSettings, stateManager);
    await splash.Show();
    WindowState = WindowState.Maximized;
    ShowInTaskbar = true;
    splash.Close();
};

I did that way to, I mean in the loadWindows event , but the behavior of the UI wasn't how I wanted , the Main Windows appears first and then show the splash.
But, thanks for sharing your experience, it help me any ways :)
