I have created a silverlight 5 project and added a textbox control to a xaml page, then added a tract action behavior to the textbox control.
Also added the ServiceOrientedAnalytics component on the main.xaml page and configured the endpoint to my wcf service. When I tried to execute the project I am getting the following error message. The same works good in SL4. I am able to track the events in SL4 and its all working fine. Could anyone help me in resolving this issue.
I also downloaded the latest source code of Microsoft Analytics from codeplex site and added to my project, when I tried to debug, the same exception is happening when it is tring to import the Log.

I have identified an issue with MEF and Silverlight 5 and I am working to resolve it. The DataCollector.Log method is not found by MEF.
