Microsoft User Interface Process Application Block 2.0

Microsoft User Interface Process Application Block (UIPAB) is a patterns & practices library from Microsoft that helps structure complex, multi-step user interactions in .NET applications. It provides a framework for modeling “user processes” as navigation flows, separating UI elements from control logic and state management. UIPAB supports both Windows Forms and ASP.NET Web Forms, allowing developers to centralize navigation behavior, maintain process state across steps, and implement features like back/forward navigation and wizard-style workflows.

Key features and benefits:

• Separation of concerns through controller classes that encapsulate UI-independent logic
• Navigation defined in configuration (XML) with support for branching and conditional transitions
• Pluggable state persistence providers (in-memory and SQL Server)
• Support for multi-step workflows such as wizards and guided tasks
• Back/forward navigation with history tracking and state sharing across views
• Extensible design for custom providers and adapters
• Works across Windows Forms and ASP.NET Web Forms to promote reuse of process logic

Note: UIPAB is an older, retired application block originally targeting the .NET Framework 1.1 era. For newer projects, consider more modern frameworks such as the Composite UI Application Block (CAB) or Prism, especially for WPF and contemporary .NET development.
