Microsoft Unity

Unity is a lightweight, extensible dependency injection container. It facilitates building loosely coupled applications and provides developers with simplified object creation especially for hierarchical object structures and dependencies, abstraction of requirements, increased flexibility by deferring component configuration to the container, service location capability, and instance and type interception.

Requirements:

Microsoft .NET Framework 3.5 Microsoft Visual Studio Development System 2008 or 2010, Microsoft Visual Studio, and Moq v3.1 assemblies.
