Tizkan/nhom1dotnet — reverse-engineered prompt

Build me a simple usable Dotnet web app from this project. There isn’t a README, so please inspect what’s already here and continue from the existing pages, models, data, and database setup instead of starting over.

I want it to feel like a small database driven site for a school project. Add a clean home page, basic navigation, and pages where a user can view the records that already exist in the app, add new ones, edit them, delete them, and see clear messages when something works or fails. Make the forms easy to use, with simple validation so blank or bad data doesn’t get saved.

Please keep the design neat and responsive enough for a laptop or phone, using the existing web assets where possible. Make sure the app runs locally without errors, the database connection is set up sensibly, and include any setup notes needed to open it and test it. Look up current docs online if you need to.
