    copied!<p>I'm working with autofac. So far i resolve all my dependencies with constructor injection.</p> <p>There is a case where i get stuck:</p> <p>Considering the given customer class:</p> <pre><code>public class Customer : ICustomer { public string Name { get; set; } private int ExternId { get; set; } public IExternalIdProvider externalIdProvider { get; set; } public Customer() { this.externalIdProvider = new ConcreteIdProvider(this); } public BevorSave() { this.ExternId = externalIdProvider.GetNextId(); } } </code></pre> <p>In Order to create a new customer object based on a request or gui action. I use the new Operator. However - There is an IdProvider within the CustomerClass i want to inject. (as property).</p> <p>If the Customer would be resolved by the ioC Container i would use a configuration like:</p> <pre><code>builder.RegisterType&lt;ConcreteIdProvider&gt;().As&lt;IExternalIdProvider&gt;(); builder.RegisterType&lt;Customer&gt;().As&lt;ICustomer&gt;() .OnActivated(ae =&gt; { IExternalIdProvider idProvider = ae.Context.Resolve&lt;IExternalIdProvider&gt;(TypedParameter.From(ae.Instance)); ae.Instance.externalIdProvider = idProvider; }); </code></pre> <p>My Question is: How can I inject the behaviour of the ExternalIdProvider in the Customer? (using autofac)</p> <p>This article shows a sample, how this would be done with a service locator: <a href="http://blogs.msdn.com/b/simonince/archive/2008/06/30/dependency-injection-is-dead.aspx" rel="nofollow">http://blogs.msdn.com/b/simonince/archive/2008/06/30/dependency-injection-is-dead.aspx</a> </p> <p>Thanks for your help.</p>
