实体框架没有更新我的表值

enter image description here

然后我有我的3个表：

CREATE TABLE [Group].[RecommendedUserGroups] 
(
[Groups_GroupId] INT NOT NULL, 
[RecommendedUsers_RecommendedUserId] int NOT NULL, 
CONSTRAINT [PK_GroupRecommendedUser] PRIMARY KEY CLUSTERED ([Groups_GroupId] ASC, [RecommendedUsers_RecommendedUserId] ASC), 
CONSTRAINT [FK_RecommendedUsers_RecommendedUserGroups] FOREIGN KEY ([RecommendedUsers_RecommendedUserId]) REFERENCES [Zinc].[RecommendedUsers] ([RecommendedUserId]), 
CONSTRAINT [FK_Groups_RecommendedUserGroups] FOREIGN KEY ([Groups_GroupId]) REFERENCES [Group].[Groups] ([GroupId]) 
) 

CREATE TABLE [Group].[Groups] 
(
[GroupId] INT NOT NULL IDENTITY(1, 1), 
[Customers_CustomerId] INT NOT NULL, 
[Name] NVARCHAR(128) NOT NULL, 
[IsArchived] BIT NOT NULL, 
[SmallImageUrl]  NVARCHAR (256) NULL, 
[MediumImageUrl]  NVARCHAR (256) NULL, 
[LargeImageUrl]  NVARCHAR (256) NULL, 
[AllowFiltering] BIT NOT NULL DEFAULT 0, 
    [IsSegment] BIT NOT NULL CONSTRAINT DF_Groups_IsSegment DEFAULT 0, 
    CONSTRAINT [PK_Groups] PRIMARY KEY CLUSTERED ([GroupId] ASC), 
    CONSTRAINT [FK_Groups_Customers] FOREIGN KEY ([Customers_CustomerId]) REFERENCES [Zinc].[Customers] ([CustomerId]),  
) 

CREATE TABLE [Zinc].[RecommendedUsers] 
(
[RecommendedUserId]     INT IDENTITY(1,1) NOT NULL,    
[Firstname]       NVARCHAR (50) NOT NULL, 
[Surname]       NVARCHAR (50) NOT NULL, 
[Email]        NVARCHAR (256) NOT NULL, 
[Department]      NVARCHAR (256) NULL, 
[JobTitle]       NVARCHAR (256) NULL, 
[DateAndTimeProcessed]    DATETIME   NULL, 
[Users_UserId]      INT    NOT NULL, 
[DateAndTimeRecommended]   DATETIME   NOT NULL, 
[AssignedUserId]     INT    NULL, 
CONSTRAINT [PK_RecommendedUsers] PRIMARY KEY CLUSTERED ([RecommendedUserId] ASC), 
)

然后我实体：

namespace Zinc.Entities 
{ 
public class RecommendedUser 
{ 
    #region Properties 

public virtual int RecommendedUserId { get; set; } 
public virtual string Firstname { get; set; } 
public virtual string Surname { get; set; } 
public virtual string Email { get; set; } 
public virtual string Department { get; set; } 
public virtual string JobTitle { get; set; } 
public virtual DateTime? DateAndTimeProcessed { get; set; } 
public virtual int Users_UserId { get; set; } 
public virtual DateTime? DateAndTimeRecommended { get; set; } 
public virtual int AssignedUserId { get; set; } 
public virtual ICollection<Group.Group> Groups { get; set; } 

#endregion 

} 
} 

namespace Zinc.Entities.Group

{ public class Group { ＃地区属性

public virtual int GroupId { get; set; } 
public virtual string Name { get; set; } 
public virtual bool IsArchived { get; set; } 
public virtual bool IsSegment { get; set; } 
public virtual bool AllowFiltering { get; set; } 

public virtual string SmallImageUrl { get; set; } 
public virtual string MediumImageUrl { get; set; } 
public virtual string LargeImageUrl { get; set; } 

public virtual Entities.Customer Customer { get; set; } 

#endregion 

#region ICollections 

//i am only concerned with recommended user so will just put this collection here 


    private ICollection<RecommendedUser> _groupRecommendedUsers; 
public virtual ICollection<RecommendedUser> RecommendedUsers 
{ 
    get 
    { 
    if (_groupRecommendedUsers == null) 
     _groupRecommendedUsers = new List<RecommendedUser>(); 

    return _groupRecommendedUsers; 
    } 
    set 
    { 
    _groupRecommendedUsers = value; 
    } 
}

所以当我保存组与recommende用户的详细信息，将其写入我的recommendeuser表，但没有更新我的RecommendedUserGroups表？

有人可以帮忙吗？我使用mvc3

RecommendedUserGroups表的主键应该是表中的两个字段。

定义表格的方式每个组只能有一个成员。
