autofac

问题 I have large wpf application. I simplify my problem with autofac. Let say I have ViewModelLocator where I create contrainer. ViewModelLocator is in Company.WPF project, this project refers Company.ViewModels project. var builder = new ContainerBuilder(); builder.RegisterType<MainWindowViewModel>().AsSelf().SingleInstance(); container = builder.Build(); Problem: MainWindowViewModel needs ICompanyService (I use CI) which is in Company.Services project, this project should not be reference from

问题 I've been trying to pass a service to a LuisDialog from the MessagesController like so: public async Task<HttpResponseMessage> Post([FromBody]Activity activity) ... await Conversation.SendAsync(activity, () => new ActionDialog(botService)); The botService is injected into the MessageController using dependency injection. When I start a bot conversation I get an error: Type 'ThetaBot.Services.BotService' in Assembly 'ThetaBot.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is

问题 Is it possible to register a component conditionally on an other component's state? Something like: ContainerBuilder.RegisterConditionally<T>( Func<IComponentContext, bool>, Func<IComponentContext, T>); I've found that prior to V2 of autofac one could use a " Register().OnlyIf() " construction that seemed like the one I'm looking for. I would like such feature to conditionally override a default registration. class CommonRegistrations { public virtual void Register(ContainderBuilder builder)

问题 I have an IFoo service implemented by DefaultFoo , and I've registered it as such in my autofac container. Now I would like to allow for an alternative implementation of IFoo to be implemented in a plugin assembly, which can be dropped in a "plugins" folder. How do I configure autofac to prefer this alternative implementation if it is present? 回答1: If you register some interface implementations, Autofac will use the latest registration. Other registrations will be overridden. In your case,

问题 I have an ASP.NET MVC web application using Autofac for dependency injection. Occasionally, this web application will start a thread to do some work separate from the request thread. When this background thread starts up, it establishes a new Autofac lifetime scope from the root container and runs some action. public IAsyncResult Run<T>(Action<T> action) { var NewTask = System.Threading.Tasks.Task.Factory.StartNew(() => { using (var Scope = Runtime.Container.BeginLifetimeScope()) { var Input

问题 Here's my problem: I have a container where I register concrete types as interfaces. builder.RegisterType<DeleteOrganization>().As<IDeleteOrganization>(); I'm implementing a SerializationBinder for a serialization project I'm doing and the BindToType method that I need to implement wants me to return a Type object. The BindToType method gives me an assemblyName and typeName (both strings) to help me create a type object. What I want to do is if the typeName is an interface, I want to ask

问题 Assuming that I have the following interface and class: public interface IFooRepo : IDisposable { //... } public FooRepo : IFooRepo { //Methods here //Properly implement the IDisposbale.Dispose() here } I use Autofac as IoC container in my application and if I register this as below, can I be sure that it will disposed properly? private static IContainer RegisterServices(ContainerBuilder builder) { builder.RegisterType<FooService>().As<IFooService>(); return builder.Build(); } Or should I

问题 Lets say I have the following service and components: public interface IService { void DoWork(); } public class ServiceA : IService { private readonly string _name; public ServiceA(string name) { _name = name; } public void DoWork() { //ServiceA DoWork implementation } } public class ServiceB : IService { private readonly string _name; public ServiceB(string name) { _name = name; } public void DoWork() { //ServiceB DoWork implementation } } Notice that each component takes a constructor

问题 .NET and Java both have a slew of DI/IoC containers available to them and each have a number of patterns that I've found very useful at various points in working with them. I'm now at a point where I would like to do equivalent things in JavaScript. As JavaScript is a dynamic language, I don't expect DI/IoC containers to have direct equivalents to all the functionality provided by the containers found in statically typed languages so alternatives to these patterns are welcome. I also expect

问题 Have anyone been successful in attaching an IoC with OWIN ASP.NET Identity to share the same DbContext as the WebApi (or MVC) application? I would like that if ASP.Net identity loads the user, it loads in the same dbcontext as used in the rest of the application. (using AutoFac as IoC - but wouldn't mind an example with other container) Edit : 06/Jan/2014: Just to be a bit more specific, when the ASP.Net identity attempts to use a DbContext it needs to be the same DbContext instance as the
