Using Autofac with Self Hosted WCF Services in a Windows Service

I was recently asked how to best create ServiceHost instances wired up with Autofac when using WCF Self Hosting in a Windows Service. In particular, how to do this in a dynamic way when the WCF services are defined in a separate assembly, without moving the service host configuration into the Windows Service entry point assembly.

Worst validation message ever

I was testing what I hoped (but doubted) would be a non-breaking change to a web service contract and got this doozy of a validation message from svcutil.exe (Microsoft Service Model Metadata Tool). The person that wrote this validation message clearly should have gone into the legal profession, because it reads more like legalise from an EULA than something a sane person is meant to understand:

WSCF.blue V1.0.13 Update

image I have posted a V1.0.13 update for WSCF.blue to address a bug with the WSDL round-tripping feature. It was reported that message headers were not being round-tripped in the WSDL when fault messages existed for the same operation. I normally prefer to batch up a few bug fixes for an update build, but I can appreciate that this particular bug would get very annoying when using headers along with numerous operations.

Fault Contract support in WSCF.blue

Adding support for fault contracts to WSCF.blue has been on my TODO list for quite a while now. It was left behind when the port to WCF was done because ASMX did not have proper support for fault contracts so it was never actually part of WSCF.classic. Back in the old ASMX days you had to manually set the Detail property in the SoapException yourself and then add the fault details to the WSDL by hand.

Making Self-Hosting with Autofac WCF Integration easier

Thinking about the sample I recently posted for shelf-hosting WCF Services with the Autofac WCF Integration, I decided that the boilerplate code for configuring the Service Behavior could be moved into an extension method on the ServiceHost instead. I have checked in some code that will extend ServiceHostBase with a new method called AddDependencyInjectionBehavior. There are two overloads of the method, one that takes a generic argument for the service contract type, and another that allows you to provide a Type for the service contract in case you are configuring your WCF Services in some sort of latebound manner. Both overloads of the method require an IContainer instance.

Self-Hosting WCF Services with the Autofac WCF Integration

A question came up recently in the Autofac group about how to use the WCF Integration when self-hosting WCF Services. This post provides a quick demonstration of how to handle the self-hosting scenario and should be enough to get you started. The example is a rather unimaginative web service that echoes back a message.
