Here's a simplified version of what I do (error handling removed). If the initialization takes a while, you may want to display a splash screen while you're doing your thing.

App.xaml:

App.xaml.cs:

namespace MyProgram
{
    public partial class App : Application
    {
        private void App_StartUp(object sender, StartupEventArgs e)
        {
            // Create the model and MainWindow
            MyModel model = CreateModel();
            MainViewModel viewModel = new MainViewModel(model);
            MainWindow = new MainWindow(viewModel); // Sets the DataContext

            // Do things, like initialize your model
            model.Initialize();

            // Now show your window
            MainWindow.Show();
        }
    }
}
