Hi Lotuslab12, thanks for reaching out us.
With regard to your issue, rather than creating a new solution/project, I recommend cloning the provided melange example and adapt it to your needs.
Starting from scratch could lead to all the needed settings not to be on place and cause your building process to fail.
Finally, be aware that Melange-related questions should go in the Melange Development category, and to make proper use of tags and Q&A functionality.
Best, Riccardo
