I get the following error when I run my project and since I am a newbie I am not sure where to start on this one.

TIA Terry Bottorff

System.InvalidOperationException was unhandled

  Message="An error occurred creating the form. See Exception.InnerException for details.  The error is: An error occurred while creating a new DataLayer for the business object."

Thank you. I recreated the whole project and apparently I did something wrong the first time because the second time it worked. Does it matter if I created a BO project in the solution because on the second try I just added a BO and not a BO project and then a BO to that project? I don't think it should... Thanks
