This extension adds support for dependency injection for WCF services and behaviors.

There are three Ninject ServiceHostFactorys which could be used in IIS host and self host.

• Ninject.Extensions.Wcf.NinjectServiceHostFactory is used for ordinary services
• Ninject.Extensions.Wcf.NinjectWebServiceHostFactory is used for REST services
• Ninject.Extensions.Wcf.NinjectDataServiceHostFactory is used for data services

There is a NinjectBehaviorExtensionElement which could resolve WCF behaviors with dependencies.
