    <p>I have a layered web application that I built with ASP.NET MVC 4, WebAPI and some other components. I'm using the latest release of Autofac 2.6.2.859 as my DI container along with the MVC and WebAPI integrations. I have autofac modules setup in my different layers and I'm using the new RegisterAssemblyModules to scan the AppDomain assemblies for the various modules.</p> <p>On startup every works great. When I edit the web.config file and the application warms up, my registrations are lost. I get a DependencyResolutionException - </p> <blockquote> <p>None of the constructors found with 'Public binding flags' on type 'My.Class.Name' can be invoked with the available services and parameters:</p> </blockquote> <p>So my registrations are not being reloaded. Does anyone know how to address this issue? Should I put my initialization code somewhere else other than Application_Start() ?</p> <p><strong>UPDATE</strong></p> <p>Here's what my code looks like</p> <pre><code> public static class IoC { public static void Configure() { var builder = new ContainerBuilder(); var assemblies = AppDomain.CurrentDomain.GetAssemblies(); //Assembly Modules builder.RegisterAssemblyModules&lt;NSUTriviaModuleBase&gt;(assemblies); // Register API controllers using assembly scanning. builder.RegisterControllers(assemblies); // Register API controllers using assembly scanning. builder.RegisterApiControllers(assemblies); var container = builder.Build(); // Set the dependency resolver implementation. var resolver = new AutofacWebApiDependencyResolver(container); GlobalConfiguration.Configuration.DependencyResolver = resolver; DependencyResolver.SetResolver(new AutofacDependencyResolver(container)); } } </code></pre>

    1. COInteresting - are you running this at debug time, e.g. in Cassini or IIS Express, or is this something you're doing in prod? :)

    2. COIt is running in debug mode on a remote staging server with IIS 6 and .NET 4.0. It works fine on IIS 7.5 Express locally. Errors only arise when there's a recycle.

    3. COAre you able to set any tracing/logging to examine the states of the DependencyResolvers when the error occurs? Are they both still the Autofac ones?

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.
