Namespace: System.Windows

Library: PresentationFramework

For the creation a subclass of Window you can use a .XAML file having the name of the subclass. By example:Window1.xaml:

<Window  
  xmlns="http://schemas.microsoft.com/winfx/avalon/2005"
  xmlns:x="http://schemas.microsoft.com/winfx/xaml/2005"
  x:Class="DMU.Window1"
     
  Title="DMU Tutorials Serie"
  Top="100"
  Left= "100"
  Width="400"
  Height="400"

  Loaded="OnLoaded"
>
  
</Window>

And you need also a Window1.xaml.cs file:

//This is a list of commonly used namespaces for a window. Not all used here.
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Media;
using System.Windows.Shapes;

namespace DMU{
 public partial class Window1 : Window{
  
  public Window1(){
   InitializeComponent();
  }

  private void OnLoaded(object sender, EventArgs e){
    //... 
  }
    
 } 
} 

At the MyApp.xaml.cs file you need to create an object of the subclass and show it:

using System;
using System.Windows;
using System.Data;
using System.Xml;
using System.Configuration;

namespace DMU{
  public partial class MyApp : Application{

    void AppStartingUp(object sender, StartupEventArgs e){
      Window1 mainWindow = new Window1();
      mainWindow.Show();
    }

  }
}

There are many properties of the Class whose values is better to assign at the .XAML file, but can be assigned at any place.

Background

The value will be a color. There are many colors available for WPF users. Some (you can find more in the SDK Documentation):
