Any one has experienced self hosting WCF inside aspn.net MVC5 project using Autofac ? What are the drawbacks if any and what are the advantages?

1.  Autofac is nothing but an open-source dependency injection (DI) or inversion of control (IoC) container developed on Google Code.Its similar to Ninject or other IOC.

I don't know what difficulty you are getting in WCF self hosting by MVC5 using Autofac.I think you can do like as given below example for WEBAPI :

Configured Autofac with ASP.Net MVC4 and WebAPI. Here are the steps required to configure Autofac

Install package Autofac.MVC4

Install package Autofac.WebApi

Add a class AutofacBootstrap. Use this class to configure the dependencies within your project.

public class AutofacBootstrap

    {

        internal static void Init(ContainerBuilder builder)

        {

        }

    }

Open Global.asax file and add a method like

private void RegisterIOC()

        {

            var builder = new ContainerBuilder();

            builder.RegisterControllers(typeof(MvcApplication).Assembly);

            builder.RegisterApiControllers(typeof(MvcApplication).Assembly);

            AutofacBootstrap.Init(builder);

            var container = builder.Build();

            DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

            GlobalConfiguration.Configuration.DependencyResolver = new Autofac.Integration.WebApi.AutofacWebApiDependencyResolver(container);

        }

Call the method from Application_Start

Its done.

B> There is a drawback and advantages of self hosting WCF with in a project or IIS.

Self-Hosting :

Needs to add code to host the process.

Host process should be running before client makes a call to the service.

Automatic process recycling not possible.

Can   controlled the service lifetime using Open and Close methods.

Easy to deploy.

IIS Hosting :

Automatic hosting.

IIS host runs automatically when a client makes a call to the service.

Automatic process recycling possible.

Lifetime cannot be controlled manually.

More difficult deployment than  Self-Hosting.

Let me know if you have any concern i will try to create sample project in MVC5 with Autofac for you.
