TFS Website Build -> The type or namespace name 'something_ascx' does not exist in the namespace 'ASP'

Question

Hello I'm trying to build a website using Team Build 2010 (TFS and stuff), but it gives me this error:

The type or namespace name 'something_ascx' does not exist in the namespace 'ASP' (are you missing an assembly reference?)

As I went to google, I found out that ASP is a 'pseudo' namespace which can't be referenced while compiling... but what I am supposed to do to make it work ?

Answer 1

Does your program builds locally? What about if you get latest version on a new machine? You may forget to check-in/update something.

Answer 2

dlls are not checked-in by default so if your building the application after several user check-ins, the dlls must be manually synchronized. I usully create a shared folder and add all the applications dlls there so that all users have the same version of them.
