ASP.NET 5 Web应用程序未在IIS Express中以调试模式运行

完全按照本教程（包括此处所述的先决条件）进行操作后，我使用上的VS2015Professional创建了Web应用程序ContosoBooks Windows 7。该应用程序成功编译，但是当我在Visual Studio中使用F5在调试模式下运行该应用程序时，它等待了很长时间，最终给了我这个错误：项目属性设置为默认值，如下所示：

Windows事件日志显示以下消息： The directory specified for caching compressed content C:\Users\myname\AppData\Local\Temp\iisexpress\IIS Temporary Compressed Files\Clr4IntegratedAppPool is invalid. Static compression is being disabled

project.json文件如下：
