Autofac attribute injection failing on attributes

阅读更多关于 Autofac attribute injection failing on attributes

问题 I've found a few questions on this, but they tend to point to the exact documentation I'm following... but it's still not working. I'm building a fairly simple ASP.NET MVC 4 site, and the plan is to use ActionFilterAttribute -based logging. I have a DataAccessProvider class which opens transactions with the database and provides unit-of-work instances, and I'm trying to inject it into the filter attribute. The documentation says that it's enough to just call RegisterFilterProvider() , and

Passing in the type of the declaring class for NLog using Autofac

阅读更多关于 Passing in the type of the declaring class for NLog using Autofac

问题 Following on from this question I would like autofac to inject the type of the declaring object into the constructor of my NLog service, so that it can correctly log which type is logging entries. My NLogService class looks like this... public class NLogService : ILogService { private readonly Logger _logger; public NLogService(Type t) { var consumerType = t.DeclaringType.FullName; _logger = LogManager.GetLogger(consumerType); } However it fails on app startup because it obviously cannot work

阅读更多关于 Managing AutoFac lifetime scopes per session and request in asp.net mvc 3

问题 I want to use AutoFac in a web application. I have the root container, a child container per session and a child container per request. I'm trying to figure out what the/a best way is to manage these lifetime scopes. In the Global.asax.cs I have added the following: protected void Application_Start(object sender, EventArgs e) { var container = ...; } protected void Session_Start(object sender, EventArgs e) { var sessionScope = container.BeginLifetimeScope("session"); Session["Autofac

Instance per matching lifetime scope, with default?

阅读更多关于 Instance per matching lifetime scope, with default?

问题 I'd like to have an instance per matching lifetime scoped registration in Autofac, but occasionally need to request an instance from a global container (where there is no matching lifetime scope). In scenarios where no matching lifetime scope exists, I want to give a top-level instance instead of throwing an exception. Is this possible? 回答1: I think you'd better extend Autofac by introducing a new lifetime option. I took the Autofac sources and modified them a bit: public static class

Autofac - resolving runtime parameters without having to pass container around

阅读更多关于 Autofac - resolving runtime parameters without having to pass container around

问题 I have a simpler "ServiceHelper" class that takes two parameters in the constructor: public ServiceHelper(ILogger<ServiceHelper> log, string serviceName) (ILogger generic wrapper for NLog that Autofac is providing just fine, and the serviceName is the name of a Windows service to control that I need to provide at runtime.) I'm having trouble wrapping my head around how to create new instances of this class at runtime passing in different service names, using Autofac. Something like this doesn

Managing NHibernate ISession with Autofac

阅读更多关于 Managing NHibernate ISession with Autofac

问题 Does anyone have any tips or best practices regarding how Autofac can help manage the NHibernate ISession Instance (in the case of an ASP.NET MVC application)? 回答1: I'm not overly familiar with how NHibernate sessions should be handled. That said, Autofac have excellent instance lifetime handling (scoping and deterministic disposal). Some related resources are this article and this question. Since you're in ASP.Net MVC land make sure you also look into the MVC integration stuff. To illustrate
