However, the Window.Icon property only accepts an ImageSource object. Does anyone know how I can 'wrap' the Canvas in an ImageSource so I can use it as a window icon? Alternativ...

I would like to use "O" as "access key" here. Unfortunately, <AccessText> does not seem to be usable directly (I imaginged something like <AccessText Visibility="...
Seems like as really simple thing to do, but I just can't track it down in the help or online. I know how to change the XAML to set the StartPoint and EndPoint of a LinearGradient brush, but I don't know how you do it using the IDE in Expression Blend - does anyone know the keyboard/mouse actions that you use to do this? ...
I've created a user control (in vb.net code) that contains two dock panels, one for header content (called HeaderDockPanel) and one for other content (called RootDockPanel).

Is it possible to deploy a WPF windows application in such a way that the xaml files can be manipulated at run-time? If possible, I would imagine this would work similar to an asp.net application that can deploy the .aspx pages as content, which are then compiled just-in-time at run-time. I'd like to allow the simple layout of a screen...
