nazimamin/HotelManagement ? reverse-engineered prompt

Build me a simple hotel management app in C# that connects to a SQL database and lets staff handle reservations and kitchen work in one place.

I want a separate login for front desk and kitchen staff, with the front desk able to add, edit, update, delete, and search entries, see room availability, and work through a clear data grid view. The kitchen side should have a to do list, an order queue for items on the line, and an overview of current occupancy. Make it feel like a clean modern desktop app with a metro style look, similar to the screenshots in the README. If it makes sense, include a way to send receipt text messages with Twilio. Keep the app simple and educational, but working end to end with basic sample logins for each role.
