Looks like this could be the key ingredient!

If you persist with it I think the results can be great I’m happy with the way it came together in Whitebox but rich client applications are much less consistent in their “lifetime structure” than the regular transaction-processing-type applications that Autofac was originally designed for.

A few example scenarios illustrate the kinds tutroial things Autofac facilitates:. Amazing stuff, I simply love it, and really want to try it out on a big project at some point.

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. But now let say we have 3 interfaces A, B, and C. Using the Autofac dependency injection container to simplify the configuration of object-oriented applications. Great article, very useful and Autofaq does seem quite a good IOC container.

Dependency Injection with Autofac – CodeProject

At application startup… Create a ContainerBuilder. It won’t be as useful a learning experience as it would tjtorial if I could walk through the steps to build it myself, but presumably I’ll be able to try it on some other project, later.

In simple terms, think about a. For questions, hit us up on StackOverflow. Download The easiest way to get Autofac is through NuGet. I’ve attempted tryresolve, tryresolvename, tryresolvetype and all fail. Unfortunately, which component should do this cleanup, and when, is not always easy to determine. Tutoroal vote of 5 Josh Smith Jan 9: In fact, it’s trivial and looks like this:.

Existing factory methods can be exposed using expressions: But, try as I might, I can’t seem to find an “easy” IoC primer or tutorial anywhere.

Each time such a component is requested from the container, a new instance will be created:. Once you provide a reference, you will find the following reference in the references section of the application.

This kind of direct object creation works well locally on a few classes, but doesn’t scale up to large numbers of components. Take a look at the official documentation.

A component can be configured to have this lifetime using the SingleInstance modifier: Wiring Up Components The ultimate structure of the application looks like: In the real world, existing components, frameworks, and architectures often come with their own unique ‘creational’ or life-cycle requirements.

Get Involved Found an issue? IDisposable is both a blessing and a curse. The process of creating the component registrations before requesting the MemoChecker service from the container is shown below:. NET application; however, the flexibility of the Autofac model tutorual a lot of integration tasks so trivial that they’re best left to the designer to implement in the way most suitable for their application.

CheckNow ; A real application, with several layers and all sorts of components, shouldn’t be configured this way.

For one thing, the code that did this at startup would get increasingly complex over time, and would potentially need to be reorganized every time the dependencies of a class change. This is one effective means of controlling architectural complexity.

Getting started with autofac

It’s really helpful to me. If a per-dependency component is required in order to construct a tutotial component, for example, then the per-dependency component will live alongside the single-instance component for the life of the container.

My vote of 5 Razan Paul Raju Aug How to instant a DbContex? It manages the dependencies between classes so that applications stay easy to change as they grow in size and complexity. Both are using Autofac as dependency injector.

I can help you getting your projects done. I’ve seen a couple of approaches work. Fine-Grained Control of Component Lifetimes The container will normally exist for the duration of an application execution, and disposing it is a good way to free resources held by components with the same application-long life-cycle.
