Main() in WPF: Unveiling the Hidden Method

For novice programmers, the concept of a program's execution starting with the Main() method is deeply ingrained. However, in WPF (Windows Presentation Foundation) projects, Main() seems to be absent. This raises the question: is Main() named differently in WPF?

Contrary to popular belief, Main() is not absent in WPF. Instead, it is created automatically by the Visual Studio IDE during project creation. However, if you prefer to define your own Main() method, here are the steps to follow:

1. Modify App.xaml Properties: Right-click on the App.xaml file in the solution explorer and select "Properties."
2. Change Build Action: Under the "Properties" tab, locate the "Build Action" property and change it from "ApplicationDefinition" to "Page."

Once these changes are made, you can add a custom Main() method to the App.xaml.cs file. It would typically look like the following:

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

By implementing these steps, you can explicitly define your Main() method in WPF projects, providing you with greater control over the program's entry point.
