F＃ - > EF生成錯誤的SQL

Question

我試圖做EF一個簡單的多到一的關係，並確定它像：

type Car() = 
    [<DefaultValue>] val mutable private id : int 
    member x.ID with get() = x.id and set(v) = x.id <- v 
    [<DefaultValue>] val mutable private carName : string 
    member x.CarName with get() = x.carName and set(v) = x.carName <- v 
    [<DefaultValue>] val mutable private dealer : Dealer 
    member x.Dealer with get() = x.dealer and set(v) = x.dealer <- v 

and Dealer() = 
    [<DefaultValue>] val mutable private id : int 
    member x.ID with get() = x.id and set(v) = x.id <- v 
    [<DefaultValue>] val mutable private name : string 
    member x.Name with get() = x.name and set(v) = x.name <- v 
    [<DefaultValue>] val mutable private cars : seq<Car> 
    member x.Cars with get() = x.cars and set(v) = x.cars <- v 

type MyContext() = 
    inherit DbContext("MyContext") 
    [<DefaultValue(true)>] val mutable private cars : DbSet<Car> 
    member x.Cars with get() = x.cars and set(v) = x.cars <- v 
    [<DefaultValue(true)>] val mutable private dealers : DbSet<Dealer> 
    member x.Dealers with get() = x.dealers and set(v) = x.dealers <- v 

，把它在控制檯啓動方式如下：

let ctx = new MyContext() 
Query.query <@ seq { for x in ctx.Cars do if x.CarName = "Volvo" then yield x.Dealer.Name } @> 

上面會生成以下SQL查詢：

SELECT 
[Extent2].[Name] AS [Name] 
FROM [dbo].[Cars] AS [Extent1] 
LEFT OUTER JOIN [dbo].[Dealers] AS [Extent2] ON [Extent1].[Dealer_ID] = [Extent2].[ID] 
WHERE N'Volvo' = [Extent1].[CarName] 

現在是我的問題，爲什麼它需要在規定的經銷商汽車類型並將其翻譯爲Dealer_ID而不是DealerID?

嘗試使用StoreName DataAnnotation attribute或Fluent mapping HasColumnName method指定此屬性的顯式映射。
