title: Autofac Property Inject issues
body: <p>I am using MVC with EF and Autofac. I have a concrete class called Helper. Helper is in another DLL and not the main MVC web application. </p>
  
  <p>It has a property of type DBContext called 'Context'. </p>
  
  <p>I want to inject an instance of the DBContext into this property - however its always null. </p>
  
  <p>Here is what I have so far in GLobal:</p>
  
  <pre><code>    var output = new DbContext(connectionString);
      builder.RegisterInstance(output).As&lt;DbContext&gt;().PropertiesAutowired();
               builder.RegisterType&lt;Helper().WithParameter("Context",output).PropertiesAutowired();
  
          // Set the dependency resolver to be Autofac.
          var container = builder.Build();
          DependencyResolver.SetResolver(new AutofacDependencyResolver(container));
  </code></pre>
  
  <p>Context is the property on the Helper class which I would like injected with the instance 'output'.</p>
  
  <p>Context is always null. </p>
