Исключение типа 'System.ArgumentException' произошло в EntityFramework.dll, но не был обработан в пользовательском коде
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?
