    <p>I'm new to Ninject and Dependency Injection in general so please excuse my noobness here. =)</p> <p>I have several implementations of an <code>IConfig</code> interface which scan an Assembly and its dependencies for types implementing an <code>IConfigOption</code> interface. Each <code>IConfig</code> implementation retrieves their values from different sources.</p> <p>These implementations take the root Assembly from where to start scanning as a constructor argument, and I'm trying to come up with a binding that injects these values. So far I'm thinking of something in the lines of:</p> <pre><code>Bind&lt;IConfig&gt;().To&lt;Config&gt;().WithConstructorArgument("rootAssembly", target); </code></pre> <p>My problem is, I can't seem to find a way to get a reference to the <code>target</code> Assembly where the <code>Config</code> class would be injected. Without DI, I would use <code>Assembly.GetCallingAssembly()</code>, but in this context this yields the Assembly where the binding resides, and not the target one as desired.</p> <p>Also, I need a way of specifying the intended implementation <strong>from the class/member that will receive the injection</strong>, so that for example, client class A asks for a <code>Config</code> implementor that uses <code>RoleEnvironment</code> and client class B asks for a <code>Config</code> implementor that uses <code>ConfigurationManager</code>. Here's an example to clarify the intended usage:</p> <pre><code>public class Client { [UseApplicationConfig] public IHelper WithAppConfig { get; set; } [UseRoleEnvironmentConfig] public IHelper WithRoleEnvironmentConfig { get; set; } } public class Helper : IHelper { public Helper(IConfig config) { } } </code></pre> <p>I get the feeling that either I'm looking at this from the wrong angle or I'm missing the obvious, but i'm not sure what I should be looking for. How would be the best way to do it?</p> <p>Thank you very much.</p> <p>EDIT: Added an example of the intended usage and rephrased some parts of the question for clarity.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
