ASP.Net5 Startup.cs ConfigurationBuilder

使用VS 2015 MVC的测试版8，我收到以下错误ASP.Net5 Startup.cs ConfigurationBuilder

"Severity Code Description Project File Line 
Error CS1503 Argument 1: cannot convert from 'string' to 'Microsoft.Framework.Configuration.IConfigurationProvider' NewInventory.DNX Core 5.0 F:\Projects\NewInventory\src\NewInventory\Startup.cs 35

从我startup.cs的这一部分：

public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv) 
     { 
      // Setup configuration sources. 

      var builder = new ConfigurationBuilder(appEnv.ApplicationBasePath) 
       .AddJsonFile("config.json") 
       .AddJsonFile($"config.{env.EnvironmentName}.json", optional: true); 

      if (env.IsDevelopment()) 
      { 
       // This reads the configuration keys from the secret store. 
       // For more details on using the user secret store see http://go.microsoft.com/fwlink/?LinkID=532709 
       builder.AddUserSecrets(); 
      } 
      builder.AddEnvironmentVariables(); 
      Configuration = builder.Build(); 
     }

当我徘徊通过ConfigurationBuilder我可以看到其寻找'ConfigurationBuilder.ConfigurationBuilder(params IConfigurationProvider[] providers)'

如何将appEnv.ApplicationBasePath更改为IConfigurationProvider数组？

我project.json是：

我知道这个问题会来，这就是为什么我Q＆A'D它。除此之外：你们正在混合使用beta5和beta8软件包，你不应该那样做。将所有内容更新到beta8。 –

@Henk Mollema谢谢Henk。请参阅我的评论以下关于我尝试将所有更新到beta8 – HendPro12

一些包被重命名。请参阅[公告回购]（https://github.com/aspnet/Announcements/issues）了解更多信息。 –

有具有appEnv.ApplicationBasePath作为参数ConfigurationBuilder没有更多的构造函数，而是有SetBasePath方法。

所以你的代码更改为：

var builder = new ConfigurationBuilder() 
       .SetBasePath(appEnv.ApplicationBasePath) 
       .AddJsonFile("config.json") 
       .AddJsonFile($"config.{env.EnvironmentName}.json", optional: true);

谢谢安迪。它告诉我ConfigurationBuilder不包含SetBasePath – HendPro12

@ HendPro12的定义根据你的'project.json'：你正在混合beta5和beta8包。这似乎不是一个好主意，试着将所有内容都改为beta8。 –

也许我在做一些错误的事情..仍然学习这个新的project.json方法而不是旧的Nuget方式。不过，我昨天浏览了该文件，并使用智能感知识别最新版本。没有测试版8的人似乎没有。 – HendPro12
