    <p>The following class takes a primitive on the constructor, so I need to tell AutoFac how to generate said value using a delegate:</p> <pre><code>public class BackgroundTaskScheduler : IStartable { private readonly IJobRunner _jobRunner; private int _triggerMilliseconds; public BackgroundTaskScheduler(IJobRunner jobRunner, int triggerMilliseconds) { _jobRunner = jobRunner; _triggerTimespan = triggerMilliseconds; } } public static class AutoFac { public static void Configure() { var builder = new ContainerBuilder(); var triggerInterval = int.Parse( ConfigurationManager.AppSettings["TaskScheduleTriggerMilliseconds"]); builder.Register( c =&gt; new BackgroundTaskScheduler(c.Resolve&lt;IJobRunner&gt;(), triggerInterval)).AsImplementedInterfaces().SingleInstance(); builder.RegisterAssemblyTypes(typeof (RegistrationController).Assembly) .AsImplementedInterfaces() .AsSelf(); IContainer container = builder.Build(); } } </code></pre> <p>However, Autofac appears to ignore my registration as evidenced by the exception it throws when resolving an instance of <code>BackgroundTaskScheduler</code>:</p> <p><strong>None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder' on type 'Delen.Server.Tasks.BackgroundTaskScheduler' can be invoked with the available services and parameters: Cannot resolve parameter 'System.Int32 triggerMilliseconds' of constructor 'Void .ctor(Delen.Server.Tasks.IJobRunner, System.Int32)'.</strong></p> <p>I've successfully used the <code>IContainerBuilder.Register</code> method before in exactly such a scenario but I've no clue why it's not working this go around. </p> <p><strong>Update 1</strong></p> <p>Changing the order of the registrations did not make a difference. </p> <p><strong>Update 2</strong></p> <p>Here's an alternative way to achieve the same result as the accepted Answer: </p> <pre><code>builder.RegisterAssemblyTypes(typeof(IJobRunner).Assembly) .Except&lt;BackgroundTaskScheduler&gt;() .AsImplementedInterfaces() .AsSelf() </code></pre>

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.
