I have a dmbl with a bunch of tables and some views where I set up an Association in the Designer from the View to the Table. Then in code I try and write some code that "uses" that association and it isn't there. I look in the designer file and I don't see anything in there either.
Strange thing is I have done this before successfully with these same tables and views in a different dbml and project. All that changed was we moved everything from a 2005 SQL Server to a 2008R2 Box.
