The documentation for Prism 4 has been completely rewritten and includes the architectural overview, design, and technical concepts for composite applications, applied patterns, two chapters covering Model-View-ViewModel (MVVM), application navigation, Stock Trader Reference Implementation (Stock Trader RI) and MVVM Reference Implementation (MVVM RI) overview, QuickStart overviews, and deployment topics. Much of this guidance is applicable even if you are not using the Prism Library, but you want to know best practices for creating composite applications
Prism 4.0 – November 2010
The guide contains the following topics:
- Patterns in the Prism Library – an overview on common patterns used in “Composite Application” & Prisim Library.
- Prism Library – the organization of the Prism Library into 4 different assemblies. (WP7 has only 2 assemblies)
- Extending Prism e.g. custom logging.
- Reference Implementations
- Appendix H: Prism Hands-On Labs

Yes, that’s right… we now have a component that is a big step toward addressing the request for an MVVM-Friendly DomainDataSource. As of this posting, that feature was the #2 requested item on the RIA Services wish list, and we’ve been pondering its design for a long time. Kyle McClellan has delivered on this and he is posting details to his blog. This feature is completely separate from the DomainDataSource, and it’s built from the ground up with ViewModel usage in mind.
Here are some specific links from Kyle’s blog:

While Silverlight 4 supports accessing COM automation components from elevated trust OOB applications, many Windows platform features are currently not available through COM automation. This makes them inaccessible to such Silverlight OOB apps. Native Extensions for Microsoft Silverlight(NESL) is an effort to incrementally build a library of components that expose select Windows 7 features through COM automation, making them easily available to Silverlight 4 OOB applications running with elevated trust. The current version of NESL provides access to Windows 7 features like Sensors, Portable Devices, Speech, Taskbar and more. NESL is made up of a set of COM automation based runtime libraries, Silverlight wrapper libraries usable from Silverlight 4 OOB applications, sample applications with source, API documentation, and a developer’s guide.
A NESL is a set of libraries for Silverlight developers that allow them to access some really cool features of Windows 7 from their Silverlight applications.
- Take advantage of sensors like accelerometers, light sensors, compasses, GPS etc.
- Access content from connected portable devices like music players and digital cameras.
- Capture and create video from webcams and screen output
- Use speech recognition and text to speech capabilities.
- Integrate with the Windows 7 taskbar (Jump Lists, Icon Overlays, Taskbar Progress etc.)

When using the Silverlight Tree View Control, you will discover that it is not easy to expand a Tree Node programmatically without using code behind. This article shows how to do that using a Behavior.
