Understanding WPF deriving WIndow class

Question

I\'m sure this is easy, but new to me for WPF using C#. I know about inheriting from classes and have done so many times such as in C# WinForms projects...

Answer 1

Your base class should just be a class file (not a Window).

So create WindowBase.cs

public class WindowBase : Window
{
    // ...
}

In MainWindow (for example) change the xaml.cs file to inherit from WindowBase instead

public partial class MainWindow : WindowBase
{
    public MainWindow()
    {
        InitializeComponent();
    }
    // ...
}

In MainWindow.xaml, include the namespace for WindowBase and change Window to base:WindowBase like this
