異常信息：
An unhandled exception was thrown by the application.
System.ObjectDisposedException: Cannot access a disposed object. A common cause of this error is disposing a context that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling Dispose() on the context, or wrapping the context in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.
之前以為：
遇到這種情況一般是異步、同步混着調用了。
檢查一下調用的地方是否為同步，但在實現函數里用異步得寫法了。
昨天在使用hangfre的時候又重現了。。。。經過不斷地google發現了一個帖子，解決了我的問題。之前的看法是錯誤的。

以后出問題了還是多去官方git上看看issue。
