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.

Josh Smith Jan 9: The As call can be included for yutorial sake of being more explicit: NET’ components into the container without the need for modifications or adapter code.
NET, and other application types. But now let say we have 3 interfaces A, B, and C.
Dependency Injection with Autofac – CodeProject
The TextWriter type is a standard. Newer Post Older Post Home. Without your help, I fear it would have been completely unintelligible.
Check out the list of integration libraries to see how to integrate Autofac with your application. GetTypes if typeof IController. A component can be configured to have this lifetime using the SingleInstance modifier: And I have to test for all cases. Dependency injection is an extremely powerful structuring mechanism, but to gain those advantages, a significant proportion of a system’s components need to be available to other components through the container.
Learn If you’re new to Autofac, the Quick Start guide is a good place to start.
I have written following code for that sample console application. Wiring Up Components The ultimate structure of the application looks like: When you resolve a component, depending on the instance scope you definea new instance of the object gets created. Use the lifetime yutorial to resolve instances of the components.
Read the Docs v: In fact, it’s trivial and looks like this: That is, manually creating scopes everywhere and sprinkling use of the container through your code zutofac not necessarily the best way to go. A dependency injection container is a collection of registrations that map services to components.
Unfortunately, which component should do this cleanup, and when, is not always easy to determine. The problem is made worse by designs that allow for multiple implementations of the same service. This is important because true to the spirit of separating usage from configuration concerns, the MemoChecker service can be used wherever necessary — even created indirectly as a dependency of another component — without worrying as to whether or not it should be cleaned up.
Getting started with autofac
Like MemoCheckerthis class accepts its dependencies through its tuorial. The next question this approach raises is how to get the view model into the tutorizl.
Download source code – Have a look at the Main function where we have created a repository of all dependency types and building the repository.
The 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.
Dependency Injection with Autofac
A registration captures the autlfac behaviour of the component within the system. With single-instance lifetime, there will be at most one instance of the component in the container, and it will be disposed when the container in which it is registered is disposed e. Parameters ; So then to extend the resolution code above with parameterisation of the VM: At application startup, we are creating a ContainerBuilder and registering our Components with it.
Stay tuned for more!!. Hey – tutoria, Sacha! In the real world, existing components, frameworks, and architectures often come with their own unique ‘creational’ or life-cycle requirements.
Note the example from above:. Auto-wiring is also very useful when components are registered via the application’s XML configuration file.
