I had an old project i started working on again. Last time i worked on it was when i had C# Express 2010, no i have 2012 and I when to add a new windows form the same way I normally do but now I am getting an error. I think something changed in 2012, I am not sure what I need to do to fix it. all the old windows forms still work normally.
Error: "'ARCode' could not be found (are you missing a using directive or an assembly reference?)"
