C# - load xaml file at runtime

I have a WPF application in C#.

I have a MainWindow class which inherits from a System.Windows.Window class.

Next I have an xaml file on my disk which I want to load at runtime:

<Window x:Class="MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Title="I want to load this xaml file">

</Window>

How can I load that xaml file at runtime? In other words, I want my MainWindow class to use exactly the mentioned xaml file, so I do not want to use the method AddChild of the MainWindow because it adds a child to the window, but I want to replace also that Window parameter. How can I achieve this?

private void ChangeXaml()
{
    var reader =new StringReader(xamlToReplaceStuffWith);
    var xmlReader =XmlReader.Create(reader);
    var newWindow =XamlReader.Load(xmlReader) as Window;
    newWindow.Show();
    foreach(var prop in typeof(Window).GetProperties())
    {
        if(prop.CanWrite)
        {
            try
            {
                //A bunch of these will fail. a bunch.
                Console.WriteLine("Setting prop:{0}", prop.Name);
                prop.SetValue(this, prop.GetValue(newWindow, null), null);
            } catch
            {
            }
        }
    }
    newWindow.Close();
    this.InvalidateVisual();
}
