有人告诉我，很可能是我的数据库设置错误导致了问题，所以下面是我的带有关键字段和查询的表。

CREATE TABLE Presentations (
    Id INT NOT NULL IDENTITY(1, 1),
    SpeakerId INT NOT NULL,

    CONSTRAINT PK_Presentations PRIMARY KEY (Id),
    CONSTRAINT FK_Presentations_Speaker FOREIGN KEY (SpeakerId) REFERENCES Speakers (Id)
)

CREATE TABLE Speakers (
    Id INT NOT NULL IDENTITY(1, 1),

    CONSTRAINT PK_Speakers PRIMARY KEY (Id)
)

当我执行以下操作时：

presentations = presentations.OrderBy(x => x.Speaker.FirstName);

生成的查询如下所示：

SELECT  [t0].[Description], [t0].[EventId], [t0].[Id], [t0].[PresentedOn], 
        [t0].[Slug], [t0].[SpeakerId], [t0].[Title], [t0].[Url]
FROM    [Presentations] AS t0
LEFT    OUTER JOIN [Speakers] AS t1 ON ([t1].[Id] = [t0].[Id])
WHERE   ([t1].[FirstName] LIKE 'B' + '%')
ORDER   BY [t1].[FirstName]

连接应该是：

LEFT    OUTER JOIN [Speakers] AS t1 ON ([t1].[Id] = [t0].[SpeakerId])

这是一个紧迫的问题，有人可以帮忙吗？

非常感谢一些帮助。
