Summary
User interfaces are a common requirement in PowerShell, and even though PowerShell is written to run as a shell it is still possible to create advanced user interfaces.
WPF includes a wide variety of different controls that can be combined to build a user interface. The initial layout of a WPF UI can be described in a XAML document, reducing the amount of code required to create the interface. A designer can be used to help generate the XAML content if required.
Simple controls such as Grid, StackPanel, and DockPanel can be used to place controls without a need to resort to absolute or coordinate-based positioning within an interface.
Controls can be given names within the XAML document allowing PowerShell to find controls to attach event handlers or change values at runtime.
Elements of the user interface can be added or changed in event handlers. A ListView control was used to demonstrate a dynamically created view of an object created in PowerShell.
