VS 2015RC中的MVC 6升级

Question

我将VS2015RC MVC 6 Web项目（DNVM）从beta5升级到beta6，并将所有依赖项都升级到beta5。 经过许多细微的调整，我认为只有一个问题。 在启动中追踪配置更改后，我发现Startup方法的签名已更改，并且包含一个无法解析的接口。

错误CS0433类型'IApplicationEnvironment'在'Microsoft.Framework.Runtime.Abstractions，Version = 1.0.0.0，Culture = neutral，PublicKeyToken = null'和'Microsoft.Framework.Runtime.Interfaces，Version = 1.0.0.0，Culture =中性，PublicKeyToken =空'Web.DNX 4.5.1 D：\\ Repositories \\ Web \\ Startup.cs 35

我尝试用nuget添加beta4抽象和接口，但是都没有用。

我错过了什么大会来升级或添加到项目？

public Startup(IHostingEnvironment env, **IApplicationEnvironment** appEnv)
        {
            var configuration = new ConfigurationBuilder(appEnv.ApplicationBasePath)
               .AddJsonFile("config.json")
               .AddEnvironmentVariables();

谢谢！

跟踪下来。

只需在project.json中使用“ Microsoft.Framework.Runtime.Abstractions”：“ 1.0.0-beta5”并删除接口依赖项（如果存在）。

我的project.json

"dependencies": {
    "EntityFramework.Commands": "7.0.0-beta5",
    "EntityFramework.SqlServer": "7.0.0-beta5",
    "Microsoft.AspNet.Authentication.Cookies": "1.0.0-beta5",
    "Microsoft.AspNet.Authentication.Facebook": "1.0.0-beta5",
    "Microsoft.AspNet.Authentication.Google": "1.0.0-beta5",
    "Microsoft.AspNet.Authentication.MicrosoftAccount": "1.0.0-beta5",
    "Microsoft.AspNet.Authentication.Twitter": "1.0.0-beta5",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta5",
    "Microsoft.AspNet.Diagnostics.Entity": "7.0.0-beta5",
    "Microsoft.AspNet.Identity.EntityFramework": "3.0.0-beta5",
    "Microsoft.AspNet.Mvc": "6.0.0-beta5",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-beta5",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta5",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta5",
    "Microsoft.AspNet.SignalR.Server": "3.0.0-beta5",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta5",
    "Microsoft.AspNet.Tooling.Razor": "1.0.0-beta5",
    "Microsoft.Framework.CodeGenerators.Mvc": "1.0.0-beta5",
    "Microsoft.Framework.CommandLineUtils": "1.0.0-beta4",
    "Microsoft.Framework.Configuration": "1.0.0-beta5",
    "Microsoft.Framework.Configuration.CommandLine": "1.0.0-beta5",
    "Microsoft.Framework.Configuration.EnvironmentVariables": "1.0.0-beta5",
    "Microsoft.Framework.Configuration.Ini": "1.0.0-beta5",
    "Microsoft.Framework.Configuration.Json": "1.0.0-beta5",
    "Microsoft.Framework.Configuration.UserSecrets": "1.0.0-beta5",
    "Microsoft.Framework.DependencyInjection": "1.0.0-beta5",
    "Microsoft.Framework.Logging": "1.0.0-beta5",
    "Microsoft.Framework.Logging.Console": "1.0.0-beta5",
    "Microsoft.Framework.Runtime.Abstractions": "1.0.0-beta5",

  },

Answer 2

我刚刚自己完成了这项工作，以上答案缺少有关Startup.cs也需要进行一些细微更改的部分，希望这可以帮助其他人从beta4升级到beta5：

在project.json依赖项中添加以下内容：

"dependencies": {
    ...
    "Microsoft.Framework.Runtime.Abstractions": "1.0.0-beta5",
    ...
  },

在您的Startup.cs中，确保您具有以下用途：

using Microsoft.Framework.Runtime;

启动方法看起来像这样（包括.Build()最后也需要）。

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{               
    Configuration = new ConfigurationBuilder(appEnv.ApplicationBasePath)
        .AddJsonFile("config.json")
        .AddEnvironmentVariables()
        .Build();
}
