Gets or sets the root node of the template.
Assembly: PresentationFramework (in PresentationFramework.dll)
A single XAML element as the immediate child of the FrameworkTemplate subclass. Templates must have a single root node. In order to generate a useful template, the element chosen as VisualTreeRootNode is expected to support a content model of its own, often a model that supports multiple child elements.
One or more elements that complete the intended template. If the element chosen as VisualTreeRootNode only supports a single child, then there can only be one element declared as VisualTreeNodeContents. It is also possible (though uncommon) to provide text content if the chosen VisualTreeRootNode supports a text content property.
