Hello Bruno, Thank you for the information, I will apply these to my project.
I ran a test where I copied the the source code for step-1 into another project in my IDE. I have everything setup the same way as my own application. I as able to compile step-1 and run it within the IDE without any issues. Maybe I am referencing something in my own code that is not being reference in the step-1 On Friday, May 4, 2018 at 8:33:27 AM UTC-4, Bruno Turcksin wrote: > > Philip, > > You can do what you are doing but this is really error prone.
