将 dnvm 从更新beta8到后，1.0.0-rc1-final我的错误Startup.cs：

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

我的项目.json：

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

      }
    }
  },

  "exclude": [

    "bower_components"
  ],
  "bundleExclude": [
    "node_modules",
    "bower_components",
    "**.kproj",
    "**.user",
    "**.vspscc"
  ]
}

我做错了什么？谢谢。如果我只是评论行：

services.AddMvc();

我有这个错误：http ://clip2net.com/clip/m446898/72b2d-clip-21kb.png?nocache=1

The Microsoft.Framework libraries are now Microsoft.Extensions.

For example, Microsoft.Framework.CodeGenerators.Mvc is now Microsoft.Extensions.CodeGenerators.Mvc

I hope this helps.

Following on and expanding a bit on Joel's answer:

I just had this issue.

In the command prompt, i ran dnvm upgrade to update my DNX.

NOTE: Make sure visual studio is closed when you run this. I had it open and it just would not work after i did the stuff below. I had a IApplicationBuilder exists in both Microsoft.AspNet.Http.Abstractions and Microsoft.AspNet.Http error because of it. So i ended up restarting my pc, and then everything worked. So maybe restart your pc, then do the following.

Switched it all to rc1-final version.

I changed my global.json to this:

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

My project.json dependencies section looks like this:

"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"
},

Notice the Microsoft.Extensions.DependencyInjection, not Microsoft.Framework

Right click on 'References' and select 'Restore Packages'. Do this after any project.json change.

Then in my Startup.cs file, i changed the reference from Microsoft.Framework to 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();
    }

}
