I have a SQL database with a stored procedure (SP). I created an Entity Framework (EF) of the of the database. In the SP I coded one of the parameters as an output parameter. The EF assigned that parameter a type of System.Data.Objects.ObjectsParameter instead of String. I went back and removed the "output" qualifier from the parameter in the SP and updated the EF from the database; however, VS is still insisting that I can't pass my string parameter because it can't be converted to a System.Data.Objects.ObjectsParameter type. How do I get VS to recognize that there has been a change to the SP and/or the EF? I've tried closing the code page and reopening it, closing VS and reopening, even rebooting - nothing seems to make VS take another look at the EF.
