Question

我试图使用autofac与asp.net 5 rc1和所有的指南我看起来似乎不适用于rc1这里是我的代码

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


        // Add application services.
        services.AddTransient<IEmailSender, AuthMessageSender>();
        services.AddTransient<ISmsSender, AuthMessageSender>();
        // Create the Autofac container builder.
        var builder = new ContainerBuilder();
        // Add any Autofac modules or registrations.
        builder.RegisterModule(new DiRegistration());
        // Populate the services.
       //This Line fails 
        builder.Populate(services);
        // Build the container.
        var container = builder.Build();
        // Resolve and return the service provider.
        return container.Resolve<IServiceProvider>();
    }

调用builder.Populate（services）时;我收到此错误

无法转换为＆＃39; Microsoft.Extensions.DependencyInjection.IServiceCollection＆＃39;到＆＃39; System.Collections.Generic.IEnumerable＆＃39; Web.DNX 4.5.1 C：\ SVN \ Datayal2 \ Web \ src \ Web \ Startup.cs 81

这是我的项目json

请帮助我确定它可能只是某些命名空间发生了变化，但我无法弄清楚如何。

Answer 1

您需要将Autofac.Framework.DependencyInjection更新为兼容rc1的软件包。您可以使用此symver 4.0.0-rc1-*始终使用最新的rc1软件包，或者如果不起作用，请安装我知道与rc1（4.0.0-rc1-177）兼容的最新特定版本（在撰写本文时）

如果出于某种原因Nuget Feed不起作用，您可能还需要添加autofac的MyGet Feed网址（https://www.myget.org/F/autofac/api/v3/index.json）。

您可以从MyGet找到所有autofac的预发布包。

此外，当您引用Autofac.Framework.DependencyInjection时，您也不需要明确引用Autofac包，因为它会自动将其下拉。这样可以避免在project.json中指定这两个版本。简而言之，您在project.json中所需要的只是：

"dependencies": {
    "Autofac.Extensions.DependencyInjection": "4.0.0-rc1-177"
}

Answer 2

好的我发现问题是一些名称空间更改看起来像autofac包与rc1兼容，但是Autofac.Extensions.DependencyInjection没有rc1 nuget包但我为了让它工作而做的是我下载了rc1 gitHub完成所有工作之后{/ 3}}。

使用ASP.net v5 RC1进行Autofac
