# Unity.Wcf
|
|
|
|
Unity.Wcf is a library that allows 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.
|
|
|
|
## How to use Unity.Wcf
|
|
|
|
*WAS hosted services*
|
|
|
|
For WAS-based hosting, first create a WcfServiceFactory `class`. You can choose any name.
|
|
The WcfServiceFactory has to extend the `UnityServiceHostFactory` and implement the `ConfigureContainer` method.
|
|
|
|
Open the WcfServiceFactory class. 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`:
|
|
```cs
|
|
public class WcfServiceFactory : UnityServiceHostFactory {
|
|
protected override void ConfigureContainer(IUnityContainer container) {
|
|
// configure container
|
|
container
|
|
.RegisterType<IService1, Service1>()
|
|
.RegisterType<IRespository<Blah>, BlahRepository>()
|
|
.RegisterType<IBlahContext, BlahContext>(new HierarchicalLifetimeManager());
|
|
}
|
|
}
|
|
```
|
|
|
|
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.
|
|
```xml
|
|
<serviceHostingEnvironment>
|
|
<serviceActivations>
|
|
<add factory="WcfService1.WcfServiceFactory" relativeAddress="./Service1.svc" service="WcfService1.Service1"/>
|
|
</serviceActivations>
|
|
<serviceHostingEnvironment>
|
|
```
|
|
|
|
*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`.
|
|
|
|
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.
