public int UserDetailID {get;set;}

public UserDetail Detail {get;set;}
}

public class UserDetail
{
public int UserDetailID {get;set;}
public string Address {get;set:}
public int UserID {get;set;}

public User User {get;set;}

}

但是,当我尝试在Visual Studio 2012中首先使用EF数据库创建相同的关系时,我遇到了麻烦.这是我的代码:

CREATE TABLE [dbo].[Users] (
[UserID]                 UNIQUEIDENTIFIER CONSTRAINT [DF_Users_UserID] DEFAULT (newid()) NOT NULL,
[UserDetailID]                 UNIQUEIDENTIFIER NOT NULL,
[Name]                      NVARCHAR (50)    NOT NULL,
CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED …
