.net core 使用Autofac

1.nuget   Autofac Autofac.Extensions.DependencyInjection

2.将Startup.cs中的ConfigureServices返回类型改为IServiceProvider

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    可以将下面代码单独放入到一个文件

   var builder = new ContainerBuilder();
    builder.Populate(services);
    builder.RegisterAssemblyTypes(typeof(Startup).Assembly).AsImplementedInterfaces();
    var Container = builder.Build();
    return new AutofacServiceProvider(Container);
}
