我創建了一個silverlight 5項目,並將一個文本框控件添加到一個xaml頁面,然後在文本框控件中添加了一個tract動作行爲。 還在main.xaml頁面上添加了ServiceOrientedAnalytics組件,並將該端點配置爲我的wcf服務。當我嘗試執行該項目時,我收到以下錯誤消息。在SL4中也是如此。我能夠跟蹤SL4中的事件,並且它的工作正常。任何人都可以幫助我解決這個問題。在SL5中使用Silverlight分析框架

我還從codeplex網站下載了最新的Microsoft Analytics源代碼,並將其添加到我的項目中,當我嘗試調試時,在導入日誌時發生同樣的異常。

錯誤消息:

有一個針對Silverlight 5的MSAF構建(至少在源代碼樹中)。您是使用該版本還是SL4版本? – 2011-12-29 17:26:42

我已經確定與MEF和Silverlight 5的問題,我正在努力解決這個問題。 DataCollector.Log方法未被MEF找到。
