Another jewel from the Patterns and Practices series: User Interface Process Application Block Overview: The User Interface Process Application Block provides a simple yet extensible framework for developing user interface processes. It is designed to abstract the control flow and state management out of the user interface layer into a user interface process layer. This enables you to write generic code for the control flow and state management of different types of applications (for example, Web applications and Windows-based applications) and helps you write applications that manage users’ tasks in complex scenarios (for example, suspending and resuming stateful tasks). This leads to simpler development and maintenance of complex applications. The User Interface Process Application Block can easily be used as a building block in your own .NET application.
