A SimpleBinding extension in Window Presentation Foundation (WPF) is established using a compact binding syntax in which all binding components are specified in a string. The simple binding string is parsed to derive a native WPF binding class. A typecast may be used to determine how the binding result will be translated from one Common Language Runtime (CLR) type to another. The typecast may be provided with the binding components or derived from properties of the target WPF dependency property.
