Introduction

This module is written to allow dependency injection in DomainServices in RIA projects.

Required References

• Autofac.dll
• System.ServiceModel.DomainServices.Server.dll (Deployed to GAC if you installed RIA Services)
• AutofacContrib.DomainServices.dll

Getting Started

Create a domain service:

    public class MyDomainService : DomainService
    {
        protected readonly ISession Session;
        protected MyDomainService(ISession session)
        {
            Session = session;
	}
		
	// Your methods
    }

Setup Global.asax by register your DomainServices, register the DomainServicesModule module from the contrib project and finally replace the DomainService factory with AutofacDomainServiceFactory.

    public class Global : HttpApplication, IContainerProviderAccessor
    {

        protected void Application_Start(object sender, EventArgs e)
        {
		 var builder = new ContainerBuilder();
		 // Register your domain services
                 builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly()).AssignableTo<DomainService>();
		 
		 // Add the RIA Services module
		 builder.RegisterModule<DomainServicesModule>(); 		
		 
		 // Build as normal
		 var container = builder.Build();
		 _containerProvider = new ContainerProvider(container);
		 
		 // Replace the DomainService.Factory with AutofacDomainServiceFactory
		 DomainService.Factory = new AutofacDomainServiceFactory(container); 
	}
		
	static IContainerProvider _containerProvider;
        public IContainerProvider ContainerProvider
        {
            get { return _containerProvider; }
        }
    }
