Oauth System.IO.FileNotFoundException:'；Microsoft.Framework.ApplicationHost'；

保存用户机密会在“Asp.Net 5 beta 7”中引发异常。具体来说，当我执行此语句时：

user-secret set Authentication:Facebook:AppId 1234567890

出现以下异常：

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Framework.ApplicationHost' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.Framework.ApplicationHost'

这在

beta 6

中正常工作。有人知道为什么会发生此异常，以及我需要做什么来修复它吗？

有一个错误。卸载旧版本并安装新版本

旧行为：

dnu commands install SecretManager

dnu commands install Microsoft.Framework.SecretManager

新行为：

dnu commands install SecretManager

dnu commands install Microsoft.Framework.SecretManager
