Hello good day.
I'm a C#/WPF expert with over 3 years of experience. I can do this task for you in less than a day. If you simply need sample on how to add, edit data in an sqllite database, I can do this for you at the price of my bid.
But if you need something extra, we can discuss about the price over chat. If you need this super fast, then award the project to me so I can work on it right away. Regards.
