Silverlight Integration Pack for Microsoft Enterprise Library 5.0

Silverlight Integration Pack for Enterprise Library is a collection of guidance and reusable application blocks designed to assist Silverlight application developers with common LOB development challenges. This release includes: Caching Application Block, Exception Handling Application Block, Logging Application Block, Policy Injection Application Block, Validation Application Block, and Unity Application Block. These blocks are designed to encapsulate recommended practices which facilitate consistency, ease of use, integration, and extensibility. The release also addresses the needs of those who would like to port their existing LOB applications, that already leverage Enterprise Library, to Silverlight

This release includes:

• Caching Application Block with support for:
  • In-memory cache
  • Isolated storage cache
  • Expiration and scavenging policies
  • Notification of cache purging
• Validation Application Block with support for:
  • Multi-level complex validation
  • Attribute-based specification of validation rules
  • Configuration-based specification of validation rules
  • Simple cross-field validation
  • Self-validation
  • Cross-tier validation (through WCF RIA Services integration)
  • Multiple rule-sets
  • Meta data type for updating entities with external classes in Silverlight
  • Rich set of built-in validators
• Logging Application Block, including:
  • Notification trace listener
  • Isolated storage trace listener
  • Remote service trace listener with support of batch logging
  • Implementation of a WCF Remote logging service that integrates with the desktop version of the Logging Application Block
  • Logging filters
  • Tracing
  • Logging settings runtime change API
• Exception Handling Application Block, including:
  • Simple configurable, policy-based mechanism for dealing with exceptions consistently
  • Wrap handler
  • Replace handler
  • Logging handler
• Unity Application Block – a dependency injection container
• Dependency injection container independence (Unity ships with the Enterprise Library, but can be replaced with a different container)
• Unity Interception mechanism, with support for:
  • Virtual method interception
  • Interface interception
• Policy Injection Application Block, including:
  • Validation handler
  • Exception Handling handler
  • Logging handler
• Flexible configuration options, including:
  • XAML-based configuration support
  • Asynchronous configuration loading
  • Interactive configuration console supporting profiles (desktop vs. Silverlight)
  • Translation tool for XAML config (needed to convert conventional XML configuration files):
    • Standalone command-line tool
    • Config console wizard
    • MS Build task
  • Programmatic configuration support via a fluent interface
• StockTrader V2 Reference Implementation

Download

Download the "Enterprise Library 5.0 Silverlight Integration Pack.msi" and install it. Alternatively, download specific application blocks from NuGet.
To get the optional configuration tool, install it separately from the Visual Studio gallery or download and install the Microsoft.Practices.EnterpriseLibrary.ConfigConsole.vsix package.

• 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

Enterprise Library 3.5 for Visual Studio 2008

Enterprise Library 3.5 for Visual Studio 2008

After releasing Enterprise Library 3.X last May, and starting the Enterprise Library Contrib project, the team is currently working on porting Enterprise Library to work with Visual Studio 2008. According to Grigori Melnik, this includes improving existing application blocks as well as guidance on how to use them. Melnik also mentions, that moving to Enterprise Library 3.5 does not include introducing new application blocks. No official date was provided, but we can expect the release to be available after February 2008, after Visual Studio 2008 is officially launched.
Together with this release we can also expect to find updated Hands On Labs that will also include labs for the Validation Application Block and Policy Injection Application Block that were introduced in Enterprise Library 3.0.

Thought I should post all the link for future reference.

This was giving a hard time even after assigning permission to the registry and following most the resolutions suggested in the above links etc. But at the end rebooting the server probably did the trick and things started working as expected.
