Quick Start

To get Autofac integrated with web forms you need to reference the web forms integration NuGet package, add the modules to web.config, and implement IContainerProviderAccessor on your Global application class.

Add the modules to web.config:

<configuration>
  <system.web>
    <httpModules>
      
      <add
        name="ContainerDisposal"
        type="Autofac.Integration.Web.ContainerDisposalModule, Autofac.Integration.Web"/>
      <add
        name="PropertyInjection"
        type="Autofac.Integration.Web.Forms.PropertyInjectionModule, Autofac.Integration.Web"/>
    </httpModules>
  </system.web>
  <system.webServer>
    
    <modules>
      <add
        name="ContainerDisposal"
        type="Autofac.Integration.Web.ContainerDisposalModule, Autofac.Integration.Web"
        preCondition="managedHandler"/>
      <add
        name="PropertyInjection"
        type="Autofac.Integration.Web.Forms.PropertyInjectionModule, Autofac.Integration.Web"
        preCondition="managedHandler"/>
    </modules>
  </system.webServer>
</configuration>

Implement IContainerProviderAccessor:

public class Global : HttpApplication, IContainerProviderAccessor
{
  // Provider that holds the application container.
  static IContainerProvider _containerProvider;

  // Instance property that will be used by Autofac HttpModules
  // to resolve and inject dependencies.
  public IContainerProvider ContainerProvider
  {
    get { return _containerProvider; }
  }

  protected void Application_Start(object sender, EventArgs e)
  {
    // Build up your application container and register your dependencies.
    var builder = new ContainerBuilder();
    builder.RegisterType<SomeDependency>();
    // ... continue registering dependencies...

    // Once you're done registering things, set the container
    // provider up with your registrations.
    _containerProvider = new ContainerProvider(builder.Build());
  }
}
