c# - EF5 一对多关系导致外键列名不正确

Question

我正在尝试仅在“多”端配置与导航的一对多关系，但似乎无法让 EF 生成正确的列名。

这是相关的架构：

QuoteItem
  Id INT PRIMARY KEY

QuoteItemFiles
  Id INT PRIMARY KEY
  QuoteItemId INT NOT NULL
  FileId INT NOT NULL

Files
  FileID INT PRIMARY KEY (legacy naming convention)

和模型：

public class QuoteItem
{
  public int Id { get; set; }
  public ICollection<QuoteItemFile> Attachments { get; set; }
}

public class QuoteItemFile
{
  public int Id { get; set; }
  public File File { get; set; }
  public QuoteItem QuoteItem { get; set; }
}

public class File
{
  public int FileID { get; set; }
}

我正在配置这样的关系：

public class QuoteItemMap()
{
  HasMany(x => x.Attachments)
    .WithRequired(x => x.QuoteItem)
    .Map(x => x.MapKey("QuoteItemId"))
    .WillCascadeOnDelete(true);
}

public QuoteItemFileMap()
{
  HasRequired(x => x.QuoteItem)
    .WithMany(x => x.Attachments)
    .Map(x => x.MapKey("QuoteItemId"))
    .WillCascadeOnDelete(true);
  HasRequired(x => x.File)
    .WithMany()
    .Map(x => x.MapKey("FileId")) <-- This isn't working
    .WillCascadeOnDelete(true);
}

当我尝试访问 QuoteItem.Attachments 时，我得到“无效的列名 'File_FileID'。 ”

为什么它不听我的MapKey("FileId")指令？
