使用带有 ASP.NET 5 和 EF7 (beta 7) 的现有数据库

Question

我正在尝试使用 ASP.NET 和 EF 7 beta 7 的空模板项目连接到我现有的数据库。这就是我的 project.json 的样子：

{
  "webroot": "wwwroot",
  "userSecretsId": "aspnet5-Titanes2015-409e9e37-b7bb-4185-b7aa-6dc336087524",
  "version": "1.0.0-*",

  "dependencies": {
    "EntityFramework.Commands": "7.0.0-beta7",
    "EntityFramework.SqlServer": "7.0.0-beta7",
    "Microsoft.AspNet.Authentication.Cookies": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Facebook": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Google": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.MicrosoftAccount": "1.0.0-beta7",
    "Microsoft.AspNet.Authentication.Twitter": "1.0.0-beta7",
    "Microsoft.AspNet.Diagnostics": "1.0.0-beta7",
    "Microsoft.AspNet.Diagnostics.Entity": "7.0.0-beta7",
    "Microsoft.AspNet.Identity.EntityFramework": "3.0.0-beta7",
    "Microsoft.AspNet.Mvc": "6.0.0-beta7",
    "Microsoft.AspNet.Mvc.TagHelpers": "6.0.0-beta7",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta7",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta7",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta7",
    "Microsoft.AspNet.Tooling.Razor": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.Abstractions": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.Json": "1.0.0-beta7",
    "Microsoft.Framework.Configuration.UserSecrets": "1.0.0-beta7",
    "Microsoft.Framework.Logging": "1.0.0-beta7",
    "Microsoft.Framework.Logging.Console": "1.0.0-beta7",
    "Microsoft.Framework.Logging.Debug" : "1.0.0-beta7",
    "Microsoft.VisualStudio.Web.BrowserLink.Loader": "14.0.0-beta7"
  },

  "commands": {
    "web": "Microsoft.AspNet.Hosting --config hosting.ini",
    "ef": "EntityFramework.Commands"
  },

  "frameworks": {
    "dnx451": { },
    "dnxcore50": { }
  },

  "exclude": [
    "wwwroot",
    "node_modules",
    "bower_components"
  ],

  "publishExclude": [
    "node_modules",
    "bower_components",
    "**.xproj",
    "**.user",
    "**.vspscc"
  ],

  "Data": {
    "DefaultConnection": {
      "ConnectionString": "Server=192.168.XX.XXX\devsql;Database=XXXXXXX;Trusted_Connection=True;user id=XXXXXX;password=XXXXXX;MultipleActiveResultSets=true"
    }
  },

  "EntityFramework": {
    "ApplicationDbContext": {
      "ConnectionStringKey": "Data:DefaultConnection:ConnectionString"
    }
  },

  "scripts": {
    "prepublish": [ "npm install", "bower install", "gulp clean", "gulp min" ]
  }
}

现在，我已经查看了所有内容 Google 并且已经检查了以下问题：

我已尝试运行以下所有命令，如这些帖子中所述：

dnx ef dbcontext scaffold "ConnectionString" EntityFramework.SqlServer
dnx . ef dbcontext scaffold "<connectionString>"
Scaffold-DbContext '<connectionString>'

每次我都会收到以下错误：

The term 'dnx' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again

我做错了什么？

从一个空的模板项目访问我的远程数据库应该是一个非常简单的过程，但我已经为此苦恼了一段时间。谁能指出我正确的方向？

Answer 1

在聊天中讨论时，我们发现从 C:\Users\<username>\.dnx\runtimes 中删除已安装的运行时并使用 dnvm upgrade 重新安装最新版本是解决方案。

提示：首先检查dnvm是否更新到最新版本。您可以使用 dnvm update-self 更新它，或者通过删除 C:\Users\<username>\.dnx\bin 文件夹和运行 this PowerShell script.

中的内容来完全重新安装它
