About the Book

Welcome to the era of software reuse! Microsoft Enterprise Library helps accelerate development by providing reusable components and guidance on proven practices. If you build applications that run on the Microsoft .NET Framework, whether they are enterprise-level business applications or even relatively modest Windows® Forms, Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), or ASP.NET applications, you can benefit from using Enterprise Library. This guide helps you to quickly grasp what Enterprise Library can do for you, presents examples, and makes it easier for you to start experimenting with Enterprise Library. Enterprise Library is made up of a series of application blocks, each aimed at managing specific cross-cutting concerns.
