c# – 实体框架4.1 RC：Code First EntityTypeConfiguration继承

我的配置基类如下所示：

public class EntityConfiguration<TEntity> : EntityTypeConfiguration<TEntity>

    where TEntity : class,IEntity {

    public EntityConfiguration() {

        HasKey( e => e.Id );

        Property( e => e.Id ).HasDatabaseGeneratedOption( DatabaseGeneratedOption.Identity );

    }

}

然后每个实体都拥有自己的特定配置类,扩展这样一个如下所示：

public class CustomerConfiguration : EntityConfiguration<Customer> {

    public CustomerConfiguration() : base() {

        // Entity specific configuration here

    }

}

它编译得很好,但是我遇到的问题是,在运行时,当EF 4.1 RC尝试创建模型时,会得到以下异常：

System.InvalidOperationException was
unhandled Message=The key component
‘Id’ is not a declared property on
type ‘Customer’. Verify that it has
not been explicitly excluded from the
model and that it is a valid primitive
property. Source=EntityFramework

如果我将CustomerConfiguration类更改为从EntityTypeConfiguration< Customer>并重复主键配置,然后它工作正常,但我失去共享通用配置的能力(DRY主体是动机).

我在这里做错了吗？
>有没有另外一种方式来共享实体之间的通用配置？

以下参考其他类：

public interface IEntity {

    int Id { get; set; }

}

public class Customer : IEntity {

    public virtual int Id { get; set; }

    public virtual string name { get; set; }

}

谢谢！
