Downloaded the demo and got Framework 2.0-VB-MicrosoftAjax to work fine.
Copied the dll to my website bin folder and copied the iis data into my webconfig
from your deployment page.
Copied the selecting-multiple-files.aspx example into my site.
Design mode shows error "tag prefix is not registered"
When I run it I get "Unknown server tag 'CuteWebUI:Uploader'."
Do i need to register the dll somewhere in my app/site or import it
to that page?
