# 🏀 Ticketing System - C#

A desktop system for managing tickets to a basketball tournament.  The application provides secure authentication, ticket sales, search, and logout.  Connected clients receive live updates about seat availability.  

Match administration (CRUD) is handled through a separate Next.js web module.

---

## ✨ Main Features

### 🔑 Login

- Cashier authenticates with username & password (passwords stored using **BCrypt**).

- On success, the desktop application opens, showing the list of matches.

### 🎟️ Ticket Sales

- Sell tickets by entering **customer name**, **address**, and **number of seats**.

- All active clients instantly see updated seat availability (**Observer pattern with gRPC streaming**).

- Sold-out matches are marked in red.

### 🔍 Search

- Search tickets by **name** and/or **address**.

- If multiple customers share the same name → all tickets are displayed.

- Results include: customer, address, match, and seats.

### 🚪 Logout

- Session invalidation.

- Clean disconnection from the server.

### ⚙️ Match Management (Next.js)

- Web module for **CRUD operations** on matches: teams, stage (semifinal, final), price, capacity, date/time.

- Login with JWT token emitted
