从NotMapped类C首先实体框架4.1 $ C $派生实体类 [英] Derive Entity class from a NotMapped class in Entity Framework 4.1 Code First

问题描述

我需要从一个不属于模型中的基类派生我的两个实体类的。

I need to derive two of my Entity classes from a base class that does not belong to the model.

[NotMapped]
public abstract class BaseClass
{
    [NotMapped]
    public string SomeProperty { get; set; }
}
public partial class Derived1: BaseClass {}
public partial class Derived2: BaseClass {}

我已经试过标记的基类，其所有属性为 [NotMapped] 但上下文初始化抛出一个错误，说我的两个派生的实体类未映射。

I have tried marking the base class and all its properties as [NotMapped] but the context initializer throw an error saying that both my derived entity classes are not mapped.

推荐答案

想通了。的[NotMapped]属性不应该被施加到基类，但只有其属性。

Figured it out. The [NotMapped] attribute should not have been applied to the base class, but only its properties.
