What the ...

Coding ASP.Net can be such a "what the **ck" experience.

Just like a while ago I was puzzle by errors saying that it didn't see "AjaxControlToolkit". But turns out after I cleaned up all the code behind, suddenly everything become sunshine. This was a bit uncool since I almost got sidetracked and wonder if I didn't include the assembly properly.

Well, at least the problem was resolved.
