Autofac WcfIntegration – Service not registered with the Autofac container

Today was my first time trying to setup Autofac with WcfIntegration.

Following the instructions to the letter (almost!) I couldn’t get it to work.

I was getting the error:

The service ‘MyService’ configured for WCF is not registered with the Autofac contain

My config was fairly simple, but I still tried changing this for a good hour!

var builder = new ContainerBuilder();
builder.Register(c => new PNRResolverService(c.Resolve()));
builder.RegisterType();
AutofacHostFactory.Container = builder.Build();

After much googling and turning up no results I went back to the wiki and checked the comments (Yes, I probably should have done this first).

I found my answer six comments down!

it looks like you need to use the fully-qualified name of your service in the .SVC file

Looks like I missed a small but very important part of the example in the wiki

And your .svc file would specify the appropriate service implementation type and host factory, like this:

<%@ ServiceHost Service="TestService.Service1, TestService" Factory="Autofac.Integration.Wcf.AutofacServiceHostFactory, Autofac.Integration.Wcf" %>

Note the Service="TestService.Service1, TestService"

I changed that one tiny bit of my .svc file from `MyProject.MyService` to MyProject.MyService, MyProject and it worked perfectly!
