Microsoft Enterprise Library is a collection of application blocks designed to assist developers with common enterprise development challenges. Application blocks are a type of guidance, provided as source code that can be used "as is," extended, or modified by developers for use in enterprise development projects.
This major release of Enterprise Library contains many compelling new features and updates that will make developers more productive. There are no new blocks; instead the team focused on making the existing blocks shine, on testability, maintainability and learnability. The new features 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 Unity 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 attributes 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
Support for the .NET 4.0 Framework and integration with Microsoft Visual Studio 2010
You may have heard that here at Google we're obsessed with speed, in our products and on the web. As part of that effort, today we're including a new signal in our search ranking algorithms: site speed. Site speed reflects how quickly a website responds to web requests.
Speeding up websites is important — not just to site owners, but to all Internet users. Faster sites create happy users and we've seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don't just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed — that's why we've decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.
