在SL5中使用Silverlight分析框架

我创建了一个silverlight 5项目，并将一个文本框控件添加到一个xaml页面，然后在文本框控件中添加了一个tract动作行为。还在main.xaml页面上添加了ServiceOrientedAnalytics组件，并将该端点配置为我的wcf服务。当我尝试执行该项目时，我收到以下错误消息。在SL4中也是如此。我能够跟踪SL4中的事件，并且它的工作正常。任何人都可以帮助我解决这个问题。在SL5中使用Silverlight分析框架

我还从codeplex网站下载了最新的Microsoft Analytics源代码，并将其添加到我的项目中，当我尝试调试时，在导入日志时发生同样的异常。

错误消息：

有一个针对Silverlight 5的MSAF构建（至少在源代码树中）。您是使用该版本还是SL4版本？ – 2011-12-29 17:26:42

我已经确定与MEF和Silverlight 5的问题，我正在努力解决这个问题。 DataCollector.Log方法未被MEF找到。
