Ninject.WebContext

Smart IoC library for your WCF application.

Installation

PM> Install-Package Ninject.WcfContext -Pre

Getting started

This library is a complet implementation of IoC with Ninject for WCF. It ease you the implementation in your WCF web service project. First you need to create an automatic injection module to define your bindings :

public class MyModule : AutoInjectionModule
{
	public override void Load()
	{
		Bind<IMyInterface>().To<IMyImplementation>();
	}
}

In Ninject, bindings are in transient scope by default. The library allow you to set the Http request as scope :

Bind<IMyInterface>().To<IMyImplementation>().InHttpScope();

When your modules are ready, you have done 95% of the work ! Start the NinjectContext in your Global.asax application start method with one line :

NinjectContext
  .Get()
  .AddModule<MyModule>()
  .UseWcf()
  .WithAutoInjection()
  .Initialize();

Now define contract & implementation for your .svc :

[ServiceContract]
public interface IMyContract
{
    [OperationContract]
    MyModel GetMyModel();
}

public class MyContract : IMyContract
{
  public IMyInterace MyInterface { get; set; }
  
  public MyModel GetMyModel()
  {
      return MyInterface.GetMyModel();
  }
}

Add Ninject.WcfContext service factory in your .svc :

<%@ ServiceHost Language="C#" Service="MyContract" Factory="Ninject.WcfContext.NinjectServiceHostFactory" %>

About AutoInjection

AutoInjection is an out of the box feature in the library but you must activate it with WithAutoInjection method. If you want to use a classic IoC implementation, don't call this method and define constructor with dependecies in parameter :

public class MyContract : IMyContract
{
	IMyInterace MyInterface { get; set; }
	
	public MyContract(IMyInterace myInterface)
	{
		MyInterface = myInterface;
	}
	
  public MyModel GetMyModel()
  {
      return MyInterface.GetMyModel();
  }
}

If you do that, you can use standard NinjectModule to define your Bind but without the use of AutoInjection, Filter can't be inject (You can inject dependencies into a constructor of an attribute).
