patterns & practices Proven practices for predictable results

Save time and reduce risk on your software development projects by incorporating patterns & practices, Microsofts applied engineering guidance that includes both production quality source code and documentation.

The guidance is designed to help software development teams:

Make critical design and technology selection decisions by highlighting the appropriate solution architectures, technologies, and Microsoft products for common scenarios

Understand the most important concepts needed for success by explaining the relevant patterns and prescribing the important practices

Get started with a proven code baseby providing thoroughly tested software and source that embodies Microsofts recommendations

The patterns & practices team consists of experienced architects, developers, writers, and testers. We work openly with the developer community and industry experts, on every project, to ensure that some of the best minds in the industry have contributed to and reviewed the guidance as it is being developed. We also love our role as the bridge between the real world needs of our customers and the wide range of products and technologies that Microsoft provides.

If you need to solve enterprise software development challenges such as validation, caching, logging, and exception handling in your Silverlight line-of-business applications, the Silverlight Integration Pack for Microsoft Enterprise Library 5.0 can help. It provides guidance and reusable Silverlight components designed to encapsulate recommended practices that facilitate consistency, ease of use, integration, and extensibility. It also helps you port your existing line-of-business applications that already use Enterprise Library to Silverlight. Note that the integration pack does not cover Silverlight for Windows Phone.

This guide will help you make the most of the Silverlight Integration Pack for Enterprise Library 5.0. It is focused on the desktop Silverlight platform and comes with an accompanying reference implementation to demonstrate how you can leverage Enterprise Library in a Silverlight application. It covers the Validation, Caching, Logging, Exception Handling, and Policy Injection Application Blocks.

Each chapter contains an overview of an application block, various techniques for applying the block, and a description of how that block was applied in the reference implementation so you can begin realizing the benefits of the Silverlight Integration Pack for Enterprise Library 5.0.
