Overview

Fundamentals of the Managed Extensibility Framework LiveLessons will teach you how to leverage the Managed Extensibility Framework part of the .NET 4.0 Framework to solve common problems encountered when developing enterprise applications.

Description

Managed Extensibility Framework (MEF) is a component of .NET Framework 4.0 for creating lightweight, extensible applications. It allows application developers to discover and use extensions with no configuration required. It also lets extension developers easily encapsulate code and avoid fragile hard dependencies. MEF not only allows extensions to be reused within applications, but across applications as well. MEF was introduced as a part of .NET 4.0 and Silverlight 4.0 and 5.0. It is available on CodePlex along with source and as a result can be used, albeit unsupported and with limitations, on version 3.5 of the framework.

MEF is used by Visual Studio 2010 for add-ons and is quickly gaining momentum. It is important for developers of modular and extensible applications to learn to master this core .NET technology. This video will provide fundamentals for using the Managed Extensibility Framework (MEF) and explain when and why to use it, as well as how to use it most effectively. Topics from basic MEF composition to advanced metadata filtering are covered.
