无法找到project.json

Question

我在VS 2015更新3中对我的项目进行了一些更新，现在我遇到了这个错误：

Severity Code Description Project File Line Suppression State Error Unable to find project.json in 'C:\Users\Julius\Documents\Projects\School\Development\In Progress\ReportBook\ReportBook.Auth' ReportBook.Auth 1

以下是带有新更新的project.json文件。只是不确定框架部分是否在正确的位置。在任何情况下都是这样的。

}

这是先前的工作直到我做了更新，
