Prism provides the following benefits:
  • Provides support for WPF and Silverlight
  • Dynamically composes user interface components
  • Application modules can be developed, tested and deployed by separate teams
  • Allows incremental adoption
  • Provides an integrated user experience
  • Helps you build applications in WPF and Silverlight that have a single code base

Even single-person projects experience benefits in creating more testable and maintainable applications using this modular approach.

"Prism" is not a port of previous smart client offerings, instead it is a new deliverable that is optimized for WPF and Silverlight. It aims to deliver a simplified approach that is more easily adoptable.

Is this applicable to all layers (service, business logic and data access layers) of a n-tiered architecture? Or is this only application to the presentation layer?

Title contains "Silverlight", it is hardly mentioned anywhere in the overview. Most of the places it mentions WPF. What is the level of support and guidence available for SL. Could anybody please clarify this? I am more interested in Silverlight. Thanks in advance for the clarification.

The Composite Application Guidance for WPF (Prism) is container agnostic, but the current release comes with out-of-the-box support for the Unity container in the Microsoft.Practices.Composite.UnityExtensions project.

So, you may implement your own container too, if you want to, but you will need to implement a façade for it as shown in Willem Meints blog post: Using Spring.NET as IOC container for Composite WPF

To get the latest release of the Composite Application Guidance for WPF, you must go here:

Hope it helps.

When building a new application shell is there an alternative already built into Prism to having to use the Castle Windsor IoC Container or is it roll your own container if you don't use Castle? Thanks, Dave
