实体框架4.1代码优先和一对多映射问题

我在映射现有数据库时遇到问题。

2张表(简化(

"SomeEntity"
Id int
Name nvarchar

和

"EntityProperty"
EntityId int
Name nvarchar

并且具有从实体到实体属性的一对多关系。

如何使用EF 4.1 Code First对此进行映射？

提前Thx。

好的(这是我的代码

class Program
    {
        static void Main(string[] args)
        {
            var context = new DataContext();
            var result = context.SomeEntity.Include(p => p.EntityProperties);
            foreach (var entity in result)
            {
                Console.WriteLine(entity);
            }
        }
    }
    public class SomeEntity
    {
        public int EntityId { get; set; }
        public string Name { get; set; }
        public virtual ICollection<EntityProperty> EntityProperties { get; set; }
        public override string ToString()
        {
            return string.Format("Id: {0}, Name: {1}", EntityId, Name);
        }
    }
    public class EntityProperty
    {
        public int EntityId { get; set; }
        public string Name { get; set; }
    }
    public class DataContext : DbContext
    {
        public DbSet<SomeEntity> SomeEntity { get { return this.Set<SomeEntity>(); } }
        protected override void OnModelCreating(DbModelBuilder modelBuilder)
        {
            modelBuilder.Entity<SomeEntity>().ToTable("SomeEntity");
            modelBuilder.Entity<SomeEntity>().HasKey(k => k.EntityId);
            modelBuilder.Entity<EntityProperty>().ToTable("EntityProperty");
            modelBuilder.Entity<EntityProperty>().HasKey(k => k.EntityId);
        }
    }

在获取属性的查询中使用Include时出现问题：

列名"SomeEntity_EntityId"无效。列名"SomeEntity_EntityId"无效。

public class SomeEntity
{
    public int SomeEntityId {get;set;}
    public string Name {get;set;}
    public ICollection<EntityProperty> EntityProperties {get;set;}
}
public class EntityProperty
{
    public int EntityPropertyId {get;set;}
    public string Name {get;set;}
}

public virtual ICollection<EntityProperty> EntityProperties {get;set}

public class SomeEntity
{
    [Key]
    public int Id {get;set;}
    public string Name {get;set;}
}
public class EntityProperty
{
    // What is PK here? Something like:
    [Key]
    public int Id {get;set;}
    // EntityId is FK
    public int EntityId {get;set;}
    // Navigation property
    [ForeignKey("EntityId")]
    public SomeEntity LinkedEntity {get;set;}
    public string Name {get;set;}
}
