在创建Silverlight Application项目的时候，是否启用Enable WCF RIA Service这个选项，Silverlight Client和Server Project 建立一个RIA Service Link关联。如果我们需要分离这种关联，可以使用WCF RIA Service Class Library项目来分离这种关联。
1.新增Silverlight Application项目，如果选中Enable WCF RIA SERVICE，则默认在Silverlight Client和Server Project之间默认建立了RIA SERVICE LINK关联。 

2.如果启用了WCF RIA SERVICE，如何去除这个RIA SERVICE LINK呢？
新增项目后会有两个项目，一个为Client，一个为Server。SERVER默认命名是xxx.Web的。如图： 

打开Silverlight Client项目属性，WCF RIA Service Link设置为No Project Set即可。

3.新增一个WCF RIA Service Class Library。在xxx.web项目新增一个文件夹Models，并新增一个类Customer。 

public class Customer

{

    [Key]

    public int CustomerId { get; set; }

    public string LastName { get; set; }

    public string FirstName { get; set; }

    public string EmailAddress { get; set; }

    public IList<Customer> GetRetrieve()

    {

        List<Customer> custList = new List<Customer>

                {new Customer()

                      { CustomerId = 1,

                        FirstName="Bilbo",

                        LastName = "Baggins",

                        EmailAddress = "bb@hob.me"},

                new Customer()

                      { CustomerId = 2,

                        FirstName="Frodo",

                        LastName = "Baggins",

                        EmailAddress = "fb@hob.me"},

                new Customer()

                      { CustomerId = 3,

                        FirstName="Samwise",

                        LastName = "Gamgee",

                        EmailAddress = "sg@hob.me"},

                new Customer()

                      { CustomerId = 4,

                        FirstName="Rosie",

                        LastName = "Cotton",

                        EmailAddress = "rc@hob.me"}};

        return custList;

    }

}

然后在SLRIA项目引用SLRIAService项目,SLRIA.WEB项目引用SLRIAService.web项目。

接着绑定数据到DataGrid。这里不细说。运行程序。会出现下面的错误提示。 

这时需要在Web.config添加下面的配置节点。

<?xml version="1.0"?>
