问题 I seem to be having some trouble creating a custom window type that derives from System.Windows.Window. There seem to be two problems that are occurring. Firstly, there's a compile-time error stating Cannot find the static member 'ContentProperty' on the type 'Control' This is in reference to the ContentPresenter element in the ControlTemplate for the custom window (see code sample for BaseWindowResource.xaml below).
