Hi There,

I have get answers about ContextMenu memory leak issue, and members offered solutions, but How can I apply the fix? I have copy the corresponding code to the projects, and built successfully. So how can I deal with the .dll files?

Here is this solution for memory leak, Would you like to tell me how to apply this fix? http://silverlight.codeplex.com/workitem/7089
