Well, I don't know anything about asp, asp.net, or silverlight, but I do have two suggestions:
1. Try asking on http://codingforums.com
. actionscript.org is mainly for actionscript related questions or supporting language questions as they relate to actionscript and you'll probably find more help there.
2. Think about switching to something else (such as Flash). I don't really know a lot about Silverlight or asp.net, but I do know that there's a lot more help available online for Flash than for Silverlight.
