Autofac is an IoC container for , Silverlight 5, Windows Store apps, and Windows Phone 8 apps. It manages the dependencies between. Now a days I am experimenting with various IoC containers and trying to implement POC and sharing with the community. This article assumes.

Simply create a lifetime scope that lives for the duration of the required life-cycle.
Obviously you need to have the interface separate from its implementation, because otherwise what would be point of having an interface? Firstly if I use NB: Expressive Registrations Using expressions for component registration makes including Autofac in an application a snap.
ASP.NET 5 Dependency Injection with Autofac
A registration captures the dynamic behaviour of the component within the system. For our sample app, we need to register all of our components classes and expose their services interfaces so things can get wired up nicely. For questions, hit us up on StackOverflow.
Once we run the application we will see the following result. Autofac’s scope model is flexible and powerful. I know you mention “ExternallyOwned ;” in your AutoFac wiki, but how I then ensure all the stuff that got provided to the SomeViewModel get cleaned up.
RegisterType t ;” By the way what is IController? Components that use a notifier have no way of knowing whether they should try to cast it to IDisposable and call Dispose or not. Register t ; This makes large numbers of components available without the overhead of registering each one, and you should definitely consider it in these situations.
Other application types may use additional Autofac integration libraries. The code using ITrackListing can remain unaware of this implementation detail.
Auutofac best way to approach it might just be to stub some of these classes out in a console app and experiment, it seems like there are quite a few approaches that can work. The first step is to add Autofac references to your project. In the example application, it is feasible that many different implementations of IMemoDueNotifier may be deployed.
Implement Dependency Injection Using Autofac IoC Container
Existing factory methods can be exposed using expressions: Check out the list of integration libraries to see how to integrate Autofac with your application.
Get Involved Found an issue? Member 2-Sep More importantly, it is hard to switch the implementations of services; e. Alexander Parra Lorenzo Feb Tagged as C 3. Want to help us improve Autofac?
Getting started with autofac
Nicholas Blumhardt May I’ve seen a couple of approaches work. Registering a Component with its Implementation Type Autofac can also create components the way that other autifac do, using reflection many optimise this scenario with MSIL-generation. Here is the output as expected.
Josh Smith Jan 9: Nick really good answers thanks for that. Instance per Lifetime Scope The final basic lifetime model is per-lifetime-scope, aktofac using the InstancePerLifetimeScope modifier: The most common lifetime settings used with Autofac are: This provides the flexibility needed to implement per-thread, per-request, or per-transaction component life-cycles. Well, I tried this and it also registered my IController interface as well, not that it matters however, it is not desired so I added ” ExternallyOwned ; The memos and Console.
Thanks for the book recommendation Graf Donnerblitzen Sep When you resolve a component, depending on the instance scope you defineaytofac new instance of the object gets created.
It can also handle property and method injection. The easiest way to get Autofac is through NuGet. A service, in this context, is a way of identifying a particular functional capability — it could be a textual name, but is more often an interface thtorial.
