SplashScreen实施后未加载WPF资源

Question

i wanted to implement a splashscreen in my wpf application, where i can show some status messages. I found a good tutorial on how to do it.

I'm using mvvm toolkit. My App.xaml has the StartupUri set to "View/Shell.xaml". This all works fine. Now I want to start the Splashscreen before the StartupUri is "called".

In the App.xaml.cs I implemented the main method like this:

[STAThread()]
    static void Main()
    {
        Splasher.Splash = new IPA.Merlin.View.ViewSplashScreen();
        Splasher.ShowSplash();

        for (int i = 0; i < 1000; i++)
        {
            MessageListener.Instance.ReceiveMessage(string.Format("Load module {0}", i));
            Thread.Sleep(1);
        }

        new App();
    }
    /// <summary>
    /// 
    /// </summary>
    public App()
    {
        StartupUri = new System.Uri("View/Shell.xaml", UriKind.Relative);

        Run();
    }

For this to run i had to change the startupobject in project prefs to this main method.

So now my Splashscreen gets called and shows the test messages and after this App() is called. I get the following error: Provide value on 'System.Windows.StaticResourceExtension' threw an exception with inner error : "Resource with the name {Locator} cannot be found

If I change the StartupUri to another Window, this windows resources also aren't found. This occours only if i change the startupobject and then call app.run myself. Without the Splashscreen all Resources are found without problems.

Can anyone help me with this because it's making me crazy

Thanks in advance

Instead of creating Main() method, you can override OnStartup method which gets called before main window gets initialized (App.xaml.cs) -

protected override void OnStartup(StartupEventArgs e)
{
   base.OnStartup(e);

   Splasher.Splash = new IPA.Merlin.View.ViewSplashScreen();
   Splasher.ShowSplash();

   for (int i = 0; i < 1000; i++)
   {
      MessageListener.Instance.ReceiveMessage(string.Format("Load module {0}", i));
      Thread.Sleep(1);
   }

   Splasher.CloseSplash();
}
