Ninject.Extensions.ChildKernel

This Ninject extension allows that child kernels can be defined. A child kernel is a Ninject kernel that has a parent kernel. All requests that it can't resolve are passed to the parent kernel.

Getting Started

Example:

public class Foo
{
  public Foo(IBar bar)
  {
    this.Bar = bar;
  }

  public IBar Bar { get; private set; }
}

public class Bar
{
}

var parentKernel = new StandardKernel();
parentKernel.Bind<Bar>().ToSelf().InSingletonScope();

var childKernel1 = new ChildKernel(this.parentKernel);
childKernel1.Bind<Foo>().ToSelf().InSingletonScope();

var childKernel2 = new ChildKernel(this.parentKernel);
childKernel2.Bind<Foo>().ToSelf().InSingletonScope();

var foo1 = childKernel1.Get<Foo>();
var foo2 = childKernel2.Get<Foo>();
var foo3 = childKernel1.Get<Foo>();

In this example foo1 and foo2 will be different instances. foo1 and foo3 are the same instance. And all share the same bar.

Note

• Objects that are resolved by the parent kernel can not have any dependency to an object defined on a child kernel. This is by design. Otherwise it would be possible to access objects on another child kernel if the object is defined as singleton.
• Since version 3.0, implicit bindngs are resolved on the child kernel and not the parent kernel anymore.
