The version (and optionally runtime and architecture) are important because your computer have multiple versions of dnx.exe. You can examine %USERPROFILE%.dnx untimes directory to see all the installed runtimes. The "sdk" part of global.json defines the version of dnx.exe from one of the runtimes which you installed.

了解 global.json 的 "projects" 部分很重要，它将在每个级别下的任何级别上扫描所有同级文件夹从目录.每个将被找到的 project.json 都将被解释为解决方案的项目.

It's important to understand about "projects" part of global.json that it will be scanned all sibling folders on any level under every from the directory. Every project.json, which will be found, will be interpreted as the project of the solution.

例如，您可以下载 ASP.NET 的某些部分并将其放在解决方案层次结构的新子文件夹中.例如，您可以下载 Entity Framework 7 的 RC1 源代码(文件) 在新的 中解压压缩文件src 文件夹内的 ef 文件夹.您会看到，在重新打开解决方案后不久，您的项目列表将越来越长，并且所有 Entity Framework 7 组件都将包含在您的解决方案中.以同样的方式，您可以在单独的目录 C:aspnetEF7 中提取下载的源并使用

You can for example download some part of ASP.NET and place it in the new subfolder of your solution hierarchy. For example you can download RC1 source of Entity Framework 7 (the file) any extract the zip-file in new ef folder inside of src folder of your project. You will see that, short time after reopening of the solution, the list of your project will be longer and longer and all Entity Framework 7 components will be included in your solution. In the same way you can extract the downloaded sources in separate directory C:aspnetEF7 and to use

{
  "projects": [ "src", "c:/aspnet/EF7" ],
  "sdk": {
    "version": "1.0.0-rc1-update1"
  }
}

您将获得相同的效果.如果您稍后决定删除调试 Entity Framework 7 的源代码，那么您应该从 global.json 中排除 "c:/aspnet/EF7"，然后在 Visual Studio 中删除以前通过在解决方案视图中选择添加的项目，然后单击 Del 键.

You will have the same effects. If you later decide to remove debugging the sources of Entity Framework 7 then you should just exclude "c:/aspnet/EF7" from global.json and then remove in Visual Studio previously added projects by selection in Solution View and click Del key.

我认为它应该清除您在文件夹结构中的可能性.

I think that it should clear the possibilities which you have in the folder structures.

另一个非常重要的可选文件，可能存在于解决方案层次结构中，是 NuGet.config 文件.它定义了 NuGet 提要，将在其中加载包.问题是有 许多 NuGet 存储库(请参阅 答案)，它们具有 ASP.NET 5 组件的不同初步版本.如果您使用确切的依赖项，例如

One more very important optional file, which could exist in the solution hierarchy, is NuGet.config file. It defines NuGet feed, where the packages will be loaded. The problem is that there are many NuGet repositories (see the answer), which have different preliminary versions of ASP.NET 5 components. If you use the exact dependencies like

"EntityFramework.MicrosoftSqlServer": "7.0.0-rc1-final"

那么你只需要在 NuGet 存储库中有明确的版本.问题是有时人们会使用像

then one need just have the explicit version in the NuGet repository. The problem is that sometimes one uses the dependency like

"EntityFramework.MicrosoftSqlServer": "7.0.0-*"

加载最新版本的包.如果您使用错误的 NuGet 提要，那么您可以获得早期的 RC2 版本，这些版本与其他 RC1 包不兼容(至少因为在 beta 版本之间重命名了许多组件).为确保您的解决方案(您的所有项目)使用 RC1，您可以将以下 NuGet.config 放置在您的解决方案文件夹中(在所有项目之上)，例如以下内容

to load the latest build of the package. If you would use wrong NuGet feed then you can get early RC2 builds, which are incompatible with other RC1 packages (at least because of renaming of many components between beta versions). To be sure that your solution (all your projects) uses RC1 you can place the following NuGet.config in your solution folder (on top of all projects) for example the following content

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageRestore>
    <clear /> <!-- ensure only the sources defined below are used -->
    <add key="automatic" value="False" />
  </packageRestore>
  <packageSources>
    <add key="AspNetVNext" value="https://www.myget.org/F/aspnetmaster/api/v3/index.json" />
    <add key="NuGet" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
  <activePackageSource>
    <add key="AspNetVNext" value="true"  />
    <add key="NuGet" value="true"  />
  </activePackageSource>
</configuration>

请参阅文档.我建议您在某个项目文件夹中打开命令行并执行

See the documentation. I recommend you to open command line in some project folder and to execute

dnu feeds list

命令.它将显示当前和父文件夹中的所有 NuGet.config 以及全局文件 %appdata%NuGetNuGet.Config 将被组合.NuGet 将在所有活动存储库中搜索包.它将是 https://api.nuget.org/v3/index.json和 https://www.myget.org/F/aspnetmaster/api/v3/index.json 在上述情况下.
