Autofac is an IoC container for Microsoft .NET. It manages the dependencies between classes so that applications stay easy to change as they grow in size and complexity. This is achieved by treating regular .NET classes as components.

Get Started

Our Getting Started tutorial walks you through integrating Autofac with a simple application and gives you some starting points for learning more.

Super-duper quick start:

Register components with a ContainerBuilder and then build the component container.

var builder = new ContainerBuilder();

builder.Register(c => new TaskController(c.Resolve<ITaskRepository>()));
builder.RegisterType<TaskController>();
builder.RegisterInstance(new TaskController());
builder.RegisterAssemblyTypes(controllerAssembly);

var container = builder.Build();

Resolve services from a lifetime scope - either the container or a nested scope:

var taskController = container.Resolve<TaskController>();

There is a growing number of application integration libraries that make using Autofac with your application a snap. Support for several popular frameworks is also available through the "Extras" packages.
