Hangfire Autofac .net core 3.1 [英] Hangfire Autofac .net core 3.1

问题描述

我正在使用Hangfire.Autofac，并尝试根据文档进行配置:

I am using Hangfire.Autofac and trying to configure it based on the documentation:

GlobalConfiguration.Configuration.UseAutofacActivator(builder.Build());

但是我得到以下异常:

Build()或Update()只能在ContainerBuilder上调用一次

Build() or Update() can only be called once on a ContainerBuilder

.Net Core是我的新手，如何启用 Autofac 配置?

I am new to .Net Core, how do I enable the Autofac Configuration?

推荐答案

确保一次调用以下方法: GlobalConfiguration.Configuration.UseAutofacActivator(builder.Build());

Make sure you call following method once: GlobalConfiguration.Configuration.UseAutofacActivator(builder.Build());

因此，基本上，您需要创建自己的构建器

So basicly, you need create your builder

var builder = new ContainerBuilder();

然后添加所有依赖项

builder.RegisterType< Database>().InstancePerBackgroundJob();

，然后调用 Build()方法.这取决于您的应用程序，在哪里更好地调用此方法.如果创建Web应用程序，请在 Startup 类中调用它.

and after this call Build() method. It depends on your app, where call this method better. If you craete a web application, call it in Startup class.
