What does Unity.WCF do?

A library that allows the simple integration of Microsoft's Unity IoC container with WCF. This project includes a bespoke InstanceProvider that creates a child container per client connection and disposes of all registered IDisposable instances once the connection is terminated.

Where do I get Unity.WCF binaries from?

You can download the code or dll from GitHub but it is strongly recommended that you use the NuGet package, downloadable from within Visual Studio.

Using the Package Manager Console, type Install-Package UnityWCF. Alternatively, you can use the Package Manager GUI and search for UnityWCF. The UnityWCF NuGet package will automatically add all the necessary references including the Unity NuGet package.

How do I use Unity.Wcf

WAS hosted services

For WAS-based hosting, right click on your svc file in the solution explorer and select View Markup. Next replace CodeBehind="Service1.svc.cs" with Factory="WcfService1.WcfServiceFactory", where WcfService1 is the namespace of your project. If you are using fileless activation and do not have an SVC file, change your web.config instead.

<serviceHostingEnvironment>
  <serviceActivations>
    <add factory="WcfService1.WcfServiceFactory" relativeAddress="./Service1.svc" service="WcfService1.Service1"/>
  </serviceActivations>
<serviceHostingEnvironment>

Open the WcfServiceFactory class that has been added to the root of your application. Add all necessary component registrations. If you are registering IDisposable components that need to be created and destroyed on a per client basis (i.e. an EntityFramework DataContext), please ensure that you use the HierarchicalLifetimeManager:

container
  .RegisterType<IService1, Service1>()
  .RegisterType<IRespository<Blah>, BlahRepository>()
  .RegisterType<IBlahContext, BlahContext>(new HierarchicalLifetimeManager());

Windows Service hosting

If you are hosting your WCF service within a Windows Service using a ServiceHost, replace the ServiceHost instance with the custom Unity.Wcf.UnityServiceHost. You will find that the UnityServiceHost takes in a Unity container as its first parameter but is otherwise identical to the default ServiceHost.

Delete the WcfServiceFactory class that has been added to the root of your application. It is not necessary for non-WAS hosting. Instead, you are free to configure Unity any way you like as long as the configured container is passed into the UnityServiceHost correctly. As with WAS hosting, if you want Unity.WCF to dispose of IDisposable components, you must register those components using the HierarchicalLifetimeManager lifestyle.
