缺少Silverlight部署数据提供者

我正在部署一个使用通过ADO.NET实体数据模型的mysql数据库的silverlight应用程序。缺少Silverlight部署数据提供者

当试图从我的主机上运行的应用程序，WCF服务工作正常，但是从WCF服务调用时，我得到了一个服务器例外：

Unable to find the requested .Net Framework Data Provider. It may not be installed. at System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName)
at System.Data.EntityClient.EntityConnection.GetFactory(String providerString).

我在web.config中的代码定义如下

<connectionStrings> 
<add name="modelEntities" 
providerName="System.Data.EntityClient" 
connectionString="metadata=res://*;provider=MySql.Data.MySqlClient;provider connection string=&quot;server=localhost;User Id=userid;password=mypass;database=mydb;&quot;"/> 
</connectionStrings>

在我的本地项目，它工作正常，因为我已经安装的.NET连接器为MySQL等主机支持.NET 3.5的LINQ和MySQL。我需要做些什么来解决这个问题？

我曾尝试加入

<system.data> 
<DbProviderFactories> 
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.2.0.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> 
</DbProviderFactories> 
</system.data>

和MySql.Data.dll和MySql.Data.Entity.dll bin文件夹，现在我得到的错误：

这是什么？为什么部署这个很难？
