Overview

Unity is a lightweight, extensible dependency injection container. This release is a port of Unity 2.0 to Microsoft Silverlight 3.0 and 4.0.

Microsoft Silverlight is a cross-browser, cross-platform implementation of the Microsoft .NET Framework for building and delivering the next generation of media experiences and rich interactive application for the Web.

In Unity 2.0 for Silverlight some capabilities and packaging of the Unity container have been adjusted in order to accommodate the differences between Silverlight and the desktop common language runtime (CLR), so. The following are the major differences:

  • XML configuration is not supported.
  • Because of differences in the Silverlight security model, only public types can be created and injected by the container. The desktop version allows you to also inject internal types.
  • The Unity interception mechanism is not supported.

For the full list of changes, please refer to the Release Notes.
