Autofac WCF integration + sessions
- by Michael Sagalovich
I am having an ASP.NET MVC 3 application that collaborates with a WCF service, which is hosted using Autofac host factory. Here are some code samples:
.svc file:
<%@ ServiceHost
Language="C#"
Debug="true"
Service="MyNamespace.IMyContract, MyAssembly"
Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %>
Global.asax of the WCF service project:
protected void Application_Start(object sender, EventArgs e)
{
ContainerBuilder builder = new ContainerBuilder();
//Here I perform all registrations, including implementation of IMyContract
AutofacServiceHostFactory.Container = builder.Build();
}
Client proxy class constructor (MVC side):
ContainerBuilder builder = new ContainerBuilder();
builder.Register(c => new ChannelFactory<IMyContract>(
new BasicHttpBinding(),
new EndpointAddress(Settings.Default.Url_MyService)))
.SingleInstance();
builder.Register(c => c.Resolve<ChannelFactory<IMyContract>>().CreateChannel())
.UseWcfSafeRelease();
_container = builder.Build();
This works fine until I want WCF service to allow or require sessions ([ServiceContract(SessionMode = SessionMode.Allowed)], or [ServiceContract(SessionMode = SessionMode.Required)]) and to share one session with the MVC side. I changed the binding to WSHttpBinding on the MVC side, but I am having different exceptions depending on how I tune it.
I also tried changing AutofacServiceHostFactory to AutofacWebServiceHostFactory, with no result.
I am not using config file as I am mainly experimenting, not developing real-life application, but I need to study the case. But if you think I can achieve what I need only with config files, then OK, I'll use them.
I will provide exception details for each combination of settings if required, I'm omitting them not to make the post too large. Any ideas on what I can do?
