How to register custom build Autofac.Module in Orchard?

问题

I have a piece of code that encapsulates functionality that isn't specific to Orchard. However i need to make it available in Orchard via dependency injection. So, I built up an Autofac Module that registers all components (types), but I can't find a way to inform Orchard's Autofac Container about it.

From what i red, there are two ways to add a module to a container:

By supplying the module at to the ContainerBuilder (usually at start-up), Or by updating the already built Container at runtime with a ContainerBuilder

I can approach the problem in the first way, but I rather do a variant of the second if there is such?

回答1:

Just add a class deriving from Autofac.Module to your Orchard module and that's it. It will get automatically picked by Orchard during the container construction.

回答2:

Piotr Szmyd's answer is fundamentally correct, but here's some more detail:

Your Orchard Module is the new .csproj that you've added to the Orchard.sln Add Autofac as a reference to that csproj (make sure you use the version included with Orchard - not nuget. See here for more details about that problem) Then add a class that derives from Autofac.Module and which implements Load(ContainerBuilder). e.g.

using System;
using Autofac;

namespace MyCustom.Module.Namespace
{
  public class LoaderModule : Autofac.Module
  {
    protected override void Load(ContainerBuilder builder)
    {
      builder.RegisterType<MyClass>().As<IMyInterface>();
    }
  }
}

As an additional note: The Autofac registration code only gets invoked at application startup time. If you are running with the site sitting locally in IIS and the code in VS, then the dynamic compilation nature of Orcahrd means that when you recompile the code, the application doesn't stop.

So in order for this Autofac registration code to be hit (and also for any channges to it to take effect) you have to iisreset to kill the application, so that it reloads the Autofac Registrations.
