Unknown Server Tag Error

Apr 23, 2008 at 12:59 AM
I'm trying build dropthings project in visual studio 2008 under .NET 3.5. There was an error when I compiled it:

Error 4 Unknown server tag 'cdd:CustomDragDropExtender'

this tag has been registered on top of the page.

<%@ Register Assembly="CustomDragDrop" Namespace="CustomDragDrop" TagPrefix="cdd" %>

I have solved this problem myself.  If anyone had same problem, flick me an email or leave message to this discussion.

To solve this problem, make sure you create your project in your "local" drive.

I created this project over a virtual drive which require credentials at the first place, this error just keep popping up every time I compile the solution. You will find many articles online talking about "unknown server tag" error in case which you don't add the namespace at the top of the page or don't register it in web.config.  Obviously, this is not the case.
