fabriciofernandes81/barberagenda ? reverse-engineered prompt

I want to build a simple app for a barbershop to keep track of appointments and the daily agenda.

It should let me add, edit, and cancel bookings, see who is coming in today, and avoid double booking the same time slot. I also want a way to store basic customer info like name, phone number, and notes about their haircut preferences. If possible, make it easy to search for a customer and see their past visits.

Keep it straightforward and easy to use, with a clean screen for today’s schedule and another place to manage customers. If you need to look up current docs online for anything, feel free to do that. Build it in C# and set it up so I can run it locally and start using it right away.
