MVC5 Autofac: The view found at was not created

I created very simple MVC 5.0 application that I push to GitHub repository: https://github.com/marxin/mvc-sample. My motivation is to execute app on Linux with mono 3.2.3.

I would like to add Autofac NuGet package (more precisely 3.3.0), that works fine for me. Problem is that if I add Autofac.Mvc5 integration package, Razor stops working with following error:

System.InvalidOperationException
The view found at '~/Views/Home/Index.cshtml' was not created.

Description: HTTP 500.Error processing request.

Details: Non-web exception. Exception origin (name of application or object): System.Web.Mvc.
Exception stack trace:

Could you please help me what's the necessary minimum that must be registered for Autofac to enable Razor view pages?

If I try aspx template, all works fine.

Thank you, Martin

OK, the problem was in web.config reference definition, please see following diff: https://github.com/marxin/mvc-sample/commit/3d5d7fef6f0284a96518852e0d892ca6205f5679

Btw. MVC5 is really not compatible with mono, but there are pull requests that will fix missing features.

Thanks

You need to register your IoC container for autofac. In your global.asax:

protected void Application_Start()
{
    var builder = new ContainerBuilder();
    builder.RegisterControllers(typeof(MvcApplication).Assembly);
    var container = builder.Build();
    DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

    // Other MVC setup...
}
