For a few weeks I have been focused on Extended Events and how they work in SQL 2008. One of things missing for the Extended Events is UI support. In fact there isn't even a SMO namespace for Extended Events as of the RTM of SQL 2008. This makes using Extended Events fairly complex, and requires that you have a firm understanding of the architecture and Metadata for the packages available.
To simplify this, I have written a C#.NET winforms application that can be used to help manage/explore extended events in SQL 2008. I posted the source as well as compiled binaries for the first release on the MSDN code gallery as an opensource project. I am sure that the code is not in keeping with design patterns or best practices, but I am not a C# developer, I am a DBA. I welcome any comments or advice on this:
