Question

将dnvm从beta8更新为1.0.0-rc1-final后，我的Startup.cs出错：

public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc(); <======= "iservicecollection does not contain a definition for add mvc(error)"
        services.AddTransient<IRepository, MongoRepository>();
    }

我的project.json：

{
  "packExclude": "*.cmd",
  "webroot": "wwwroot",
  "version": "1.0.0-*",
  "dependencies": {
    "Kestrel": "1.0.0-*",

    }
  },

  "exclude": [

  "bundleExclude": [
    "node_modules",
    "bower_components",
    "**.kproj",
    "**.user",

}

我做错了什么？谢谢。如果我只是评论行：

services.AddMvc();

Answer 1

Microsoft.Framework库现在是Microsoft.Extensions。

例如，Microsoft.Framework.CodeGenerators.Mvc现在是Microsoft.Extensions.CodeGenerators.Mvc

我希望这会有所帮助。

继续关注乔尔的回答：

我刚遇到这个问题。

在命令提示符下，我运行dnvm upgrade来更新我的DNX。

注意：确保运行此工作室时关闭visual studio。我把它打开了，只是在我做了下面的事情后才会不工作。因为它我有IApplicationBuilder exists in both Microsoft.AspNet.Http.Abstractions and Microsoft.AspNet.Http错误。所以我最终重新启动我的电脑，然后一切正常。所以也许重新启动电脑，然后执行以下操作。

将其全部切换到rc1-final版本。

我将global.json更改为：

{
  "projects": [ "src" ],
  "sdk": {
    "version": "1.0.0-rc1-final"
  }
}

我的project.json依赖项部分如下所示：

"dependencies": {
    "Microsoft.AspNet.Server.IIS": "1.0.0-*",
    "Microsoft.AspNet.Mvc": "6.0.0-rc1-final",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-rc1-final",
    "Microsoft.Extensions.DependencyInjection": "1.0.0-rc1-final"
},

请注意Microsoft.Extensions.DependencyInjection，而不是Microsoft.Framework

右键点击＆＃39;参考＆＃39;并选择恢复包＆＃39;。在任何project.json更改之后执行此操作。

然后在我的Startup.cs文件中，我将引用从Microsoft.Framework更改为Microsoft.Extensions：

using Microsoft.AspNet.Builder;
using Microsoft.Extensions.DependencyInjection;


public class Startup
{

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();
    }

    public void Configure(IApplicationBuilder app)
    {
        app.UseMvc();
    }

}

将dnvm更新为1.0.0-rc1-final后出错
