Using LINQ to SQL Classes in VS2005

I am having a devil of a time setting up LINQ for SQL in VS2005.  I have fx3.5 setup, have installed fx3.5SP1, etc, etc.  What googling has shown me is when I want to add a LINQ to SQL Classes item to my project I should see something like the first image.  Instead, what I am seeing is the second image.



Please note some very fundamental differences between the two images.  I should have Categories, I do not.  I should see LINQ items, I do not…

Any suggestions?  I do not have the option to upgrade to VS2008 yet.
