Unity Application Block

Unity Application Block - May 2008

The Unity Application Block (Unity) is a lightweight, extensible dependency injection container with support for constructor, property, and method call injection. It provides developers with the following advantages:

It provides simplified object creation, especially for hierarchical object structures and dependencies, which simplifies application code.
It supports abstraction of requirements; this allows developers to specify dependencies at run time or in configuration and simplify management of crosscutting concerns.
It increases flexibility by deferring component configuration to the container.
It has a service location capability; this allows clients to store or cache the container. This is especially useful in ASP.NET Web applications where the developers can persist the container in the ASP.NET session or application.

Following topic includes a series of brief sections that provide information to help you decide whether the Unity Application Block is suitable for your requirements.
