无法解决目标框架“DNX,Version=v4.5.1"的以下依赖项 [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，我只想在新的 Core CLR 上运行，所以我从我的 project.json<中的依赖项中删除了 "dnx451": { }/代码> 文件.我现在在 IIS 中启动时收到以下错误:

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:

无法解析目标框架DNX,Version=v4.5.1"的以下依赖项:Microsoft.AspNet.Mvc 6.0.0-beta4Microsoft.AspNet.Server.IIS 1.0.0-beta4Microsoft.AspNet.Server.WebListener 1.0.0-beta4Microsoft.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 可以在 Core CLR 上运行?为什么我必须包含 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

将 dnxcore50 指定为 project.json 中的依赖项与告诉解决方案目标不同那个dnx.为了解决这个问题，我必须修改解决方案 global.json 文件以使用特定版本的 dnx(即特定的 .Net 可执行文件).我还必须更改一些 using 语句以使用新的 Core CLR 库而不是 .Net 4.5 库.您将收到有关这些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 文件可以在解决方案节点下找到.我不得不添加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

Note that you can also edit this in a GUI:
