title: ASP.Net: The type or namespace name 'namespace ' could not be found (are you missing a using directive or an assembly reference?
body: <p>This should be an easy fix.
  I created a Linq to SQL class using SQLMetal.
  I added it to my project and put it in the App_Code folder. See below
  Yet intellisence is not picking up the namespace in my Default.aspx.cs code. See below.
  So when I build I naturally get an error as above.
  What should I do to fix this bug?</p>
  
  <p>The generated Linq to SQL class in the App_Code folder begins as;</p>
