Re: The AutofacServiceHost.Container static property must be set before services can be instantiated

[Alex Meyer-Gleaves]

Hi Daniel,

You should probably build your container in the Application Start event in the Global.asax.cs file instead of in your custom service host.

The steps for hosting in IIS are:

1. In your global application startup...
1. Build a Container where your service type is registered.
2. Set AutofacHostFactory.Container with this built container.
2. Update your .svc files to use the AutofacServiceHostFactory (for BasicHttpBinding or WSHttpBinding services) or theAutofacWebServiceHostFactory (for WebHttpBinding services).

See the documentation below for more information:

https://code.google.com/p/autofac/wiki/WcfIntegration#IIS_Hosted_Services

Also, if you do want to use a custom service factory you need to reference it in the .svc file.

<%@ ServiceHost Language="C#" Debug="true" Service="WCFService.MyService, WCFService" Factory="WCFService.MyServiceFactory, WCFService"%>

Cheers,

Alex.

I just downloaded a new version of autofac, autofac.web and autofac.integration.  I am learning how to host a service in iis.  I have implemented a simple service which I am able to self-host it.  However, when I try to host it in IIS,  I got the error

"The AutofacServiceHost.Container static property must be set before services can be instantiated"

 

I am grateful for your help.  The code is

 

namespace WCFService
{
    [ServiceContract]
    public interface IMyService
    {
        [OperationContract]
        string Hello();
    }

    public class MyService : IMyService
    {
        public string Hello()
        {
            return "Hello WCF";
        }
    }
}

 

namespace WCFService
{
    public class MyServiceFactory : AutofacServiceHostFactory
    {
        protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
        {
            var builder = new ContainerBuilder();
            builder.Register(c => new ChannelFactory<IMyService>(new BasicHttpBinding(), new EndpointAddress("http://localhost/MyWcfService")))
                   .SingleInstance();

            builder.Register(c => c.Resolve<ChannelFactory<IMyService>>().CreateChannel()).UseWcfSafeRelease();

            builder.RegisterType<MyService>().As<IMyService>();
            Container = builder.Build();

            var address = new Uri("http://localhost:8080/MyWcfService");
            var host = new ServiceHost(typeof (MyService), address);
            host.AddServiceEndpoint(typeof (IMyService), new BasicHttpBinding(), string.Empty);

            host.AddDependencyInjectionBehavior<IMyService>(Container);

            host.Description.Behaviors.Add(new ServiceMetadataBehavior {HttpGetEnabled = true, HttpGetUrl = address});

            return host;
        }
    }

}

 

and the MyService.svc file is

 

<%@ ServiceHost Language="C#" Debug="true"
Service="WCFService.MyService, WCFService"    
Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf"%>

 

Thank you very much.

Daniel
