EntityFramework.dll中出现“System.ArgumentException”类型的异常，但未在用户代码中处理 [英] An exception of type 'System.ArgumentException' occurred in EntityFramework.dll but was not handled in user code

问题描述

I've faced a problem that is:

An exception of type 'System.ArgumentException' occurred in EntityFramework.dll but was not handled in user code

Additional information: The Include path expression must refer to a navigation property defined on the type. Use dotted paths for reference navigation properties and the Select operator for collection navigation properties.
How can I solve it?
