无法解决目标框架'DNX，Version = v4.5.1'的以下依赖关系 [英] Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1'

问题描述

我使用的是ASP.NET 5.0，我想只在新的Core CLR上运行，因此我从<中删除了 dnx451：{} code> project.json 文件。在IIS中启动时，我现在得到以下错误：

I'm using ASP.NET 5.0 and I wanted to run just on the new Core CLR, so I removed "dnx451": { } from dependencies in my project.json file. I now get the following error when I launch in IIS:

无法解决目标框架'DNX，Version = v4的以下依赖关系。 5.1'：
Microsoft.AspNet.Mvc 6.0.0-beta4
Microsoft.AspNet.Server.IIS 1.0.0-beta4
Microsoft.AspNet.Server.WebListener 1.0.0-beta4
Microsoft.AspNet.StaticFiles 1.0.0-beta4

Failed to resolve the following dependencies for target framework 'DNX,Version=v4.5.1': Microsoft.AspNet.Mvc 6.0.0-beta4 Microsoft.AspNet.Server.IIS 1.0.0-beta4 Microsoft.AspNet.Server.WebListener 1.0.0-beta4 Microsoft.AspNet.StaticFiles 1.0.0-beta4

我的理解是AspNet.Mvc 6将在Core CLR上运行？为什么然后我必须包含 dnx451 作为依赖项？

My understanding was that AspNet.Mvc 6 would run on Core CLR? Why then do I have to include dnx451 as a dependency?

我的 project.json 文件：

{
  "webroot": "wwwroot",
  "version": "1.0.0-*",

  "dependencies": {
    "Microsoft.AspNet.Mvc": "6.0.0-beta4",
    "Microsoft.AspNet.Server.IIS": "1.0.0-beta4",
    "Microsoft.AspNet.Server.WebListener": "1.0.0-beta4",
    "Microsoft.AspNet.StaticFiles": "1.0.0-beta4"
  },

  "commands": {
    "web": "Microsoft.AspNet.Hosting --server Microsoft.AspNet.Server.WebListener --server.urls http://localhost:5000"
  },

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

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

推荐答案

在 project.json 中将 dnxcore50 指定为依赖项不是与告诉解决方案以 dnx 为目标相同。为了解决这个问题，我不得不修改解决方案 global.json 文件以使用 dnx 的特定版本（即特定的.Net可执行文件）。我还不得不更改一些 using 语句，以使用新的Core CLR库而不是.Net 4.5库。您将获得有关这些信息的智能感知和错误警告。

Specifying dnxcore50 as a dependency in project.json is not the same as telling the Solution to target that dnx. To fix this I had to modify the solution global.json file to use a specific version of the dnx (i.e. a specific .Net executable). I also had to change a few using statements to use new Core CLR libraries instead of .Net 4.5 libraries. You will get intellisense and error warnings about these.

global.json 文件可在解决方案节点下找到。我必须添加sdk版本部分：

The global.json file can be found under the Solution node. I had to add the sdk version part:

{
    "projects": [ "src", "test" ],
    "sdk": {
        "version": "1.0.0-beta4"
    }
}

请注意，您也可以在GUI中进行编辑：
