Question

I have the following hierarchy of classes:

abstract MyWindowBase : System.Windows.Window (i.e. the WPF one)

MyWindow : MyWindowBase

I want to create a Window of type MyWindow as a root element in XAML. I found only this way of doing it:

<local:MyWindowBase
    x:Class="MyWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    local:x="clr-namespace:MyProjectNamespace">

    <local:MyWindowBase.Resources>...</local:MyWindowBase.Resources>

    ...

</local:MyWindowBase>

I.e. I’m specifing my abstract type as the root element, which seems awkward.

I also tried the obvious way:

<Window
    x:Class="MyWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    ...
</Window>

and defining MyWindow : MyWindowBase in code-behind, but it clashes with the class definition in the generated file which says MyWindow : Window.

Is there a better way?
Thanks

Check this recent post of mine which explains exactly this sort of thing – how to derive one page from another (the methodology is exactly the same).
