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,如果我将所述应用程序更新并将其Nuget软件包更新到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,还是一些环境问题？

恢复日志看起来很好:

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:

    "scripts": {

    }
}

已安装最新的SDK.

根据https://github.com/dotnet/core/issues/267:当使用nuget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.

为我手动添加"type":"platform"到project.json文件解决了问题.

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

并且还要求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)将针对此问题提供解决方法.
