I have got to say that you guys are the most responsive group when it comes to fixing bugs. Many of the problems I have posted about have specifically been addressed in a subsequent release of your dotConnect for Oracle or Entity Developer products. This one wasn't even a complaint and you fixed it anyway. Thank you! Please keep up the great customer service, you guys are awesome!

Let me say first, that the DevArt DotConnect for Oracle is fantastic. It solved the problem perfectly, which was to use LINQ with Oracle. The Entity Developer tool is amazing--I can make a data change and it compiles immediately.
