在SL5中使用Silverlight分析框架

我已经创建了一个silverlight 5项目，并向xaml页面添加了一个textbox控件，然后向textbox控件添加了一个tract操作行为。 还在

main.xaml

页面上添加了

ServiceOrientedAnalytics

组件，并将端点配置为我的wcf服务。当我试图执行该项目时，我收到以下错误消息。在SL4中同样适用。我能够跟踪SL4中的事件，并且一切正常。谁能帮我解决这个问题

我还从codeplex网站下载了Microsoft Analytics的最新源代码，并将其添加到我的项目中。当我尝试调试时，在尝试导入日志时也会发生相同的异常

错误消息：

我已经发现了MEF和Silverlight 5的一个问题，我正在努力解决它。MEF找不到DataCollector.Log方法

Silverlight 5有一个MSAF的构建（至少在源代码树中）。您使用的是该版本还是SL4版本？
