Overview

This release of Unity is a port of Unity Application Block 1.2 to Microsoft Silverlight 2.0.

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.

Silverlight has some differences from the desktop common language runtime (CLR), so some capabilities and packaging of the Unity container have been adjusted in this release. The following are the major differences:

  • The single Microsoft.Practices.Unity.dll file in the Silverlight version contains all the classes from the three separate desktop DLLs: Microsoft.Practices.Unity.dll, Microsoft.Practices.ObjectBuilder2.dll, and Microsoft.Practices.Unity.StaticFactoryExtension.dll. You only need to reference and deploy the one assembly in your Silverlight projects.
  • 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.
  • XML configuration is not supported.
  • The Unity interception mechanism is not supported.

Audience Requirements

A working knowledge of the .NET Framework programming and Silverlight is required.

System Requirements

The following are the minimum system requirements to develop applications using Unity for Silverlight:

  • Windows Server 2008, Windows Vista, or Windows XP operating system
  • Microsoft Visual Studio 2008 SP1 with the Visual Web Developer feature or Microsoft Visual Web Developer 2008 Express with SP1
  • Microsoft Silverlight 2.0 SDK. This is included with Silverlight Tools for Visual Studio 2008 SP1.

The following are the minimum system requirements to run applications using Unity for Silverlight:
