ASP.NET Core 1.0.1 打破了项目

Question

如果我使用 Visual Studio 2015 Update 3 创建一个新的 ASP.NET Core MVC 应用程序，它运行得很好。但是，如果我使用该应用程序并将其 Nuget 包更新到 ASP.NET Core 1.0.1，我会收到以下构建错误：

Can not find runtime target for framework '.NETCoreApp,Version=v1.0' compatible with one of the target runtimes: 'win10-x64, win81-x64, win8-x64, win7-x64'. Possible cause
1. The project has not been restored or restore failed - run `dotnet restore`
2. The project does not list one of 'win10-x64, win81-x64, win8-x64, win7-x64' in the 'runtimes' section.
3. You may be trying to publish a library, which is not supported. Use `dotnet pack` to distribute libraries.

这是一个错误，还是环境问题？

恢复的日志看起来不错：

log  : Restoring packages for <path to project>\project.json...
log  : Restoring packages for tool 'Microsoft.AspNetCore.Server.IISIntegration.Tools' in E:\Software Projects\subq\src\SubQ.API\project.json...
log  : Lock file has not changed. Skipping lock file write. Path: <path to project>\project.lock.json
log  : <path to project>\project.json
log  : Restore completed in 6210ms.

project.json 看起来像这样：

        "Microsoft.AspNetCore.Mvc": "1.0.1",
        "Microsoft.AspNetCore.Server.IISIntegration": "1.0.0",

            ],

    }
}

已安装最新的 SDK。

根据https://github.com/dotnet/core/issues/267： 使用 nuget 更新时，“type”:“platform” 被删除，这实际上将项目更改为独立项目，因此会强制要求运行时部分。

对我来说，手动添加 "type" : "platform" 到 project.json 文件解决了这个问题。

    "dependencies": {
       "Microsoft.NETCore.App": {
          "version": "1.0.1",
          "type": "platform"
        },

还与https://github.com/dotnet/core/issues/267 合作： 通过 NuGet UI 调用更新到项目系统以更新 project.json，“type”：“platform”在该编辑期间被删除。 NuGet 3.5.0 RTM（尚未发布）将提供解决此问题的方法。

我认为runtimes 应该放在frameworks 设置之外。改变

"frameworks": {
    "netcoreapp1.0": {
        "imports": [
            "dotnet5.6",
            "portable-net45+win8"
        ],
        "runtimes": {
            "win10-x64": {}
        }
    }
},

到

"frameworks": {
    "netcoreapp1.0": {
        "imports": [
            "dotnet5.6",
            "portable-net45+win8"
        ]
    }
},  
"runtimes": {
    "win10-x64": {},
    "win81-x64": {}
},

我还必须添加 win81-x64，因为我在 Windows 8.1 上运行，编译器对此表示抱怨。

让我知道这是否有效！
