autofac

I have a project with Caliburn.Micro, and I'm trying to port from its SimpleContainer to Autofac . I'm using this code , that is an updated version of the code in this guide . Using SimpleContainer I simply did (inside the bootstrapper) protected override void OnStartup(object sender, System.Windows.StartupEventArgs e) { this.DisplayRootViewFor<IScreen>(); // where ShellViewModel : Screen } Now this doesn't work anymore, so what should I do to integrate Autofac with Caliburn.Micro ? There are a couple of things wrong with your solution. Firstly, nothing invokes your AppBootstrapper . This is

Question How do I construct an AutoFac ContainerBuilder such that my sub-dependencies are correctly resolved (assuming more than one concrete implementation of an interface)? Default registration/resolve will not work because I have more than one concrete implementation of a sub-dependency, and the sub-dependency resolution is dependent on the resolution of the primary object. In all cases I wish to use constructor injection. Scenario For example, lets say I need to print a receipt, so I create an interface called IReceipt, with one method, called PrintReceipt(). But I need to print 3 kinds of

public class MultithreadTester { public void Run() { var builder = new ContainerBuilder(); builder.RegisterType<ManualWork>().As<IWork>(); builder.RegisterType<ColabManualWork>().As<IColabWork>(); builder.RegisterType<RelaxAfterManualWork>().As<IRelax>(); var container = builder.Build(); //#1 - Simple single thread using (var scope = container.BeginLifetimeScope()) { var work = scope.Resolve<IWork>(); work.DoWork(); } //#2 - Resolving dependecies in worker threads in scopes of these threads without passing lifetime scopes are container into implementation using (var scope = container

I'm trying to set up dependency injection with Autofac for project using MVC5 and EF6. I'm having a hard time figuring out how to decouple correctly the EntityFramework.RoleStore<EntityFramework.IdentityRole> implementation. I would like have dependency only on Identity.IRoleStore<Identity.IRole> but I'm aware that for generic classes I need to specify the concrete implementation, not the interface. This is what I tried: builder.RegisterType<IdentityRole>().As<IRole>(); builder.RegisterType<RoleManager<IRole>>(); builder.RegisterType<RoleStore<IdentityRole>>().As<IRoleStore<IRole>>(); builder

I want to register a generic delegate that resolves itself at runtime, but I cannot find a way to do this on generics. Given a delegate that looks like this: public delegate TOutput Pipe<in TInput, out TOutput>(TInput input); And given a discretely registered delegate that look like this: public class AnonymousPipe<TInput, TOutput> { public Pipe<TInput, TOutput> GetPipe(IContext context) {...} I want to register a function along the lines of this: builder.RegisterGeneric(typeof(Pipe<,>)).As(ctx => { var typeArray = ctx.RequestedType.GetGenericArguments(); // this can be memoized var

I need to get or access to my IoC container in a static class. This is my (simplified) scenario: I register dependencies for ASP .net Web Api in a Startup class (but also I do this for MVC or WCF. I have a DependecyResolver project, but for simplicity, consider the following code) // Web Api project - Startup.cs public void Configuration(IAppBuilder app) { HttpConfiguration config = new HttpConfiguration(); var builder = new ContainerBuilder(); // ... Omited for clarity builder.RegisterAssemblyTypes(AppDomain.CurrentDomain.GetAssemblies()) .AsClosedTypesOf(typeof(IHandle<>))

I got an error when my GeneratePasswordResetTokenAsync() method is call. I configured autofac with owin identity. The error is : No IUserTokenProvider is registered when using dependency injection In my sample.web project there is a AutofacConfig.cs file where I register signinmanager and usermanager which I created in sample.repository project. AutofacConfig.cs public class AutofacConfig { public static Autofac.IContainer RegisterDependencies() { var containerBuilder = new ContainerBuilder(); // REGISTER DEPENDENCIES containerBuilder.RegisterType<SampleDataContext>() .As<DbContext>()

I need to get, from an IComponentContext , a list of registered Type 's that implement a particular interface. I don't want actual instances of the types, but rather a list of Type of which I could get instances. I want to use this list to generate subscriptions on a message bus. How do I get all registered implementations of an interface in Autofac? I figured this out -- var types = scope.ComponentRegistry.Registrations .SelectMany(r => r.Services.OfType<IServiceWithType>(), (r, s) => new { r, s }) .Where(rs => rs.s.ServiceType.Implements<T>()) .Select(rs => rs.r.Activator.LimitType); With
