scope of variables with App_Code folder

[Rotsey]

Hi,

I have a web site being developed with VS2005.

I am upgrading a VS2003 application by copying each page one at a time
and fixing problems. Also I have copied across my class object code
to the App_Code folder.

The problem I am having is in a class in the App_Code folder I refer to a
user
control that exists in a folder off the root of the project.
But it does not compile and says it doesn not recongize the user control
class.

Surely anything in the App_Code folder should have scope for whole
project???

Is there something I am missing like should I be reffring to the namespace
of the project and find the user control class from there??? If so what is
the namespace
of a web site project???

Thanks, happy holidays
