autofac

问题 I'm trying to do something like in my DbContext : public System.Action<IEnumerable<EntityEntry>> OnSave; public override int SaveChanges() { if(OnSave != null) OnSave(ChangeTracker.Entries()); return base.SaveChanges(); } Then DI (AutoFac) the DbContext into another class which can hook into the 'OnSave' function. I'm looking for a single source of truth when this happens. I don't think this will work or be reliable when DbContext is injected into multiple places since I'm pretty sure we end

问题 I have a piece of code that encapsulates functionality that isn't specific to Orchard. However i need to make it available in Orchard via dependency injection. So, I built up an Autofac Module that registers all components (types), but I can't find a way to inform Orchard's Autofac Container about it. From what i red, there are two ways to add a module to a container: By supplying the module at to the ContainerBuilder (usually at start-up), Or by updating the already built Container at

问题 I am building a generic piece of middleware software (a windows service) that will perform many jobs .. such as: Sync Inventory Import Orders etc I am using C# with a Windows Service, and Quartz.NET to schedule the jobs to run. I am also using AutoFac. From what I understand, AutoFac dependencies should be built at the composition root. This is fine..however, I have certain services that get injected which require runtime parameters (configuration values that come from the database). For

问题 I have a class MyResource in my application that looks like this: public class MyResource : IMyResource { // ... whatever ... } And when I initialize my application in App.xaml.cs I have something like that using Autofac: builder.Register<IMyResource>(container => new MyResource()); Now I need to add a StaticResource in a Window of my WPF application, something like this: <Window.Resources> <local:MyResource x:Key="MyResource" /> </Window.Resources> But of course, the whole idea is not to

问题 I want to write a factory for creating various types of "xxNotification" classes. My concrete "xxNotification" has dependencies registered with AutoFac. I would like to get/resolve instance of "xxNotification" using Autofac. How to do that? public interface INotification { void Notify(string Action, int OrderID); } public class MagentoOrderStateNotification : INotification { private readonly GenericRepository<Order> _orderRepository; private readonly OMRestIntegrationService

问题 I have an IRepository< T > interface with many T's and several implementations (on-demand DB, web service, etc.). I use AutoFac to register IRepository's for many T's depending on the kind of repository I want for each T. I also have a .NET-caching-based implementation that looks for T's in cache and then calls a 'real' IRepository.Find to resolve a cache miss. It is constructed something like this: new CachingRepository(realRepository, cacheImplementation); I would like to use a

问题 I'm trying to figure out a way to inject dependencies into my AuthorizeAttribute in SignalR similar to the way it is done in WebAPI. In Web API I know I can call builder.RegisterWebApiFilterProvider(config); but I can't quite seem to find an equivalent for SignalR. The closest thing I can find that looks like it might do the trick is the PropertiesAutowired() method. I have tried builder.RegisterType<MyAuthorizationAttribute>.PropertiesAutowired(); where my attribute looks like public class

问题 I may have been searching for the wrong stuff, looking in the wrong boxes. But I can't seem to find a good way to visualize how deep my dependecy tree is in C#. I've initially tried just hooking up on the preparing-event & the activating-event from Autofac. But I can't figure out if this is good enough. The results looks kinda funky. It seems that the preparing-event is initiated too often. And it seems that the activating event is only activated when a new object is actually created. Our

问题 I am adding IoC to an already existing web forms project, and I am having a little trouble with getting the dependencies of user controls injected, especially dynamic user controls in a master page. On the master page, I load some user controls: protected override void OnLoad(EventArgs e) { bool processComplete = false; var page = Page as BasePage; if (page != null && HttpContext.Current.User.Identity.IsAuthenticated) processComplete = page.processComplete ; var segments = this.Request.Url
