问题 I'm working on a Windows Service with a number of self-hosted WCF services. I'm using Autofac for DI/IoC. WCF services and endpoints are set up in app.config, and by enumerating the configured services, the Windows service is able to automatically create and open a ServiceHost for each configured WCF service. To enable dependency injection, I add a call to the AddDependencyInjectionBehavior (docs) method for each new instance of ServiceHost , but the method specifically requests a

However, with the config below _dalForValidation is never set in on Models.App , in other words the default empty constructor is always being called. private static void ConfigureAutofac() { var builder = new ContainerBuilder(); builder.RegisterApiControllers(Assembly.GetExecutingAssembly()); builder.RegisterType<DataAccessFacade>().As<IDataAccess>()

Could not load type Castle.Proxies.IReadinessProxy when running xUnit integration tests in parallel with Autofac

问题 I am having an issue that I've been many days unable to resolve. I use xUnit with a given-then-when abstraction to make tests more readable. I am using a wrapper over EventStore and running some integration tests. They all go well.. except one that fails when running all in parallel (and xUnit runs in parallel), but if I run them all sequentially they all succeed. I cannot understand why this would be an issue because every single fact is supposed to run the constructor (the given) and the

问题 How could I setup my chosen DI for this kind of setup: public abstract class BaseRepo { public BaseRepo(string token) { } } public RepoA : BaseRepo, IRepoA { // implementation of interface here } public ViewModelA { IRepoA _repo; public ViewModelA(IRepoA repo) { this._repo = repo; } public DoMethod() { this._repo.DoSomeStuff(); } } In real scenario, the token parameter on the base class is resolved after the user has been logged in. I was thinking of just configuring the interfaces for DI
