How Does a WPF Application Run Without an Explicit `Main()` Method?

WPF Without Main() Method?

You're starting out with programming and have learned about the Main() method as the starting point of any program. However, in WPF projects, you may have noticed its absence. Don't worry; it's not a different programming paradigm.

Understanding WPF's Program Start

While it's true that many programming languages require a Main() method as the entry point, WPF takes a different approach. The Main() method is automatically generated in a WPF application. It's located within the App.xaml.cs file, where the App class serves as the primary application class.

Customizing the Main() Method

If you want to customize the Main() method, you can make some adjustments. Here's how:

1. Right-click App.xaml in the solution explorer and select "Properties."
2. Change "Build Action" from "ApplicationDefinition" to "Page."
3. Add a Main() method to App.xaml.cs with the following code:

[STAThread]
public static void Main()
{
    var application = new App();
    application.InitializeComponent();
    application.Run();
}

By following these steps, you can define a custom Main() method for your WPF application and control its initialization and execution.
