问题 I want to create a Serilog Enricher injecting some data from a dependency. How can autofac inject my dependency into an enricher? This is my container setup: builder.Register((c, p) => { return new LoggerConfiguration() .Enrich.FromLogContext() .Enrich.With<MyEnricherWhichCanAddMoreDataFromADependency>() // ... .CreateLogger(); }).As<ILogger>(); While the enricher would look something like public class MyEnricherWhichCanAddMoreDataFromADependency : ILogEventEnricher { public

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.AddControllersWithViews()

Autofac ASP.NET Web API (Beta) Integration

由 ╄→гoц情女王★ 提交于 2021-02-19 01:57:36
With the beta release of ASP.NET MVC 4 and the ASP.NET Web API being released a few weeks ago, I decided it was about time to have a look at what the integration story would like for Autofac.

Support both the web hosting and self hosting scenarios in a single assembly. Avoid taking dependencies on the System.Web

Given a ContainerBuilder, can I register a missing dependency handler?

问题 I am trying to make a method with the following signature: void Chain(ContainerBuilder builder, IServiceProvider fallbackServiceProvider) { // ... } The idea is that Chain can be used as follows: IServiceProvider fallbackProvider = someExternalProvider; var builder = new ContainerBuilder(); // Custom registration might happen before and/or after the call to Chain builder.Register<MyCustomService>().As<IMyCustomService>(); builder.Register<MyExternalServiceReplacement>.As<IExternalService>();

SignalR 2, Autofac, OWIN WebAPI will not pass message from server to hub

问题 I have tried several variations over the past several weeks and so far all I can do is pass a message from the UI to the server and back. I am unable to pass a message from my controller or other method outside the hub to the UI. It seems like I am not getting an instance of the HubContext. I've created a basic demo app from scratch and uploaded here: https://github.com/cdecinkoKnight/SignalRDemo-help I have a basic hub (MessageHub): [HubName("messages")] public class MessageHub : Hub,
