DockFloat provides a way to pop WPF elements into floating windows.

To use it, install via NuGet then wrap an element in a Dock:

<df:Dock xmlns:df="clr-namespace:DockFloat;assembly=DockFloat">
    <TextBlock Text="This can be floated."/>
</df:Dock>

• Dock has some optional configuration properties.
• There is a working demo in the source code.
• Implicit styles outside the Dock have no affect in the floated window. Styles with x:Key do.
