Microsoft published a set of Hands-on Labs for EntLib 5.0. It is available for download here.

Use this set of Hands-on Labs as a guide to learn about the application blocks included with Microsoft Enterprise Library 5.0 and practice how to leverage their capabilities in various application contexts. It includes Caching, Configuration Sources, Cryptography, Data Access, Exception Handling, Interception, Logging, Security, Validation, and Unity Hands-on Labs.

Get it while it’s hot. Microsoft just published the bits of EntLib 5.0 on the Microsoft Downloads web site. This major release of Enterprise Library contains many compelling new features and updates that will make developers more productive. These include:

• Major architectural refactoring that provides improved testability and maintainability through full support of the dependency injection style of development
• Dependency injection container independence (Unity ships with Enterprise Library, but you can replace it with a container of your choice)
• Programmatic configuration support, including a fluent configuration interface and an XSD schema to enable IntelliSense
• Redesign of the configuration tool to provide:
  • A more usable and intuitive look and feel
  • Extensibility improvements through meta-data driven configuration visualizations that replace the requirement to write design time code
  • A wizard framework that can help to simplify complex configuration tasks
• Data accessors for more intuitive processing of data query results
• Asynchronous data access support
• Honoring validation attributes between Validation Application Block and DataAnnotations
• Integration with Windows Presentation Foundation (WPF) validation mechanisms
• Support for complex configuration scenarios, including additive merge from multiple configuration sources and hierarchical merge
• Optimized cache scavenging
• Better performance when logging
• A reduction of the number of assemblies
• Support for the .NET 4.0 Framework and integration with Microsoft Visual Studio 2010
• Improvements to Unity

Although it is not explicitly mentioned, it also integrates with Visual Studio 2008:
