autofac

原文: asp.net core3.0 mvc 用 autofac 好久没有写文章了，最近在用.net core3.0,一些开发中问题顺便记录； 1.首先nuget引入 Autofac Autofac.Extensions.DependencyInjection 2.修改Program.cs 添加.UseServiceProviderFactory(new AutofacServiceProviderFactory()) public class Program { public static void Main(string[] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .UseServiceProviderFactory(new AutofacServiceProviderFactory()) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }); } 3.修改Startup.cs 添加 services

On ASP.NET MVC 2 I have an ActionFilterAttribute called [Transaction] that starts an NHibernate transaction before executing the action and commits or rolls it back afterward, depending on whether or not an exception was thrown. The ISession instance is HttpRequestScoped() and injected by Autofac . It looks like this and works great: [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class)] public sealed class TransactionAttribute : ActionFilterAttribute { private ITransaction transaction; public TransactionAttribute() { this.Order = 0; } public ISession Session { get; set; } public

I noticed I quite often need to implement composite pattern. For example: interface IService { ... } class Service1 : IService { ... } class Service2 : IService { ... } class CompositeService : IService { public CompositeService(IEnumerable<IService> services) { ... } ... } I want to register CompositeService as IService in container and have dependencies injected. (looks somewhat similar to Decorator but decorating set of services instead of only one) What's the best way to do it in autofac? How would ideal solution look like (for C#)? Update: My current registration is: builder.RegisterType

I am trying to get autofac working with an mvc6 application I am working on. I found this blog article however it seems to be a little dated. It looks like its using the beta3 bits I am using this clr version 1.0.0-beta5-11911 My project has these 2 references "Autofac": "4.0.0-alpha2", "Autofac.Dnx": "4.0.0-alpha2", Within the article is talks about how to modify the startup.cs // Create the Autofac container builder. var builder = new Autofac.ContainerBuilder(); // Add any Autofac modules or registrations. builder.RegisterModule(new AutofacModule()); // Populate the services. builder

In Caliburn.Micro documentation the authors mention such possibility: documentation link IHandle inherits from a marker interface IHandle. This allows the use of casting to determine if an object instance subscribes to any events. This enables simple auto-subscribing if you integrate with an IoC container. Most IoC containers (including the SimpleContainer) provide a hook for being called when a new instance is created. Simply wire for your container’s callback, inspect the instance being created to see if it implement IHandle, and if it does, call Subscribe on the event aggregator. How is it
