Question

如果我使用Visual Studio 2015 Update 3创建新的ASP.NET Core MVC应用程序，它运行得很好。但是，如果我使用所述应用并将其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？

恢复中的日志看起来很好：

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",

安装了最新的SDK。

根据https://github.com/dotnet/core/issues/267：当使用nuget进行更新时，“类型”：“平台”被删除，这有效地将项目更改为独立，因此将强制要求运行时段。

我手动将“type”：“platform”添加到project.json文件中解决了这个问题。

>>> arr = [1, 2, 4, 3]
>>> print(", " . join(arr))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: sequence item 0: expected string, int found
>>> sarr = [str(a) for a in arr]
>>> print(", " . join(sarr))
1, 2, 4, 3
>>>

并且还要https://github.com/dotnet/core/issues/267：通过NuGet UI更新调用项目系统以更新project.json，“type”：在编辑期间删除“platform”。 NuGet 3.5.0 RTM（尚未发布）将解决此问题。

我认为runtimes应该放在frameworks设置之外。变化

"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，并且编译器抱怨它。

让我知道这是否有效！

ASP.NET Core 1.0.1打破了项目
