🧠 Quiz Master (WPF Application)

Quiz Master is a feature-rich desktop assessment tool built with WPF and the MVVM pattern. It allows users to create, edit, and play custom quizzes with dynamic category selection.

🏗 Architecture & Design Patterns

The project structure strictly follows the Model-View-ViewModel (MVVM) pattern to ensure testability and separation of concerns.

1. 📂 DataModels (The "M" in MVVM)

located in /DataModels

• Question.cs & Quiz.cs: POCO classes representing the core domain entities.
• Separation: Keeping models separate ensures the data layer is decoupled from the UI.

2. 🎮 ViewModels (The "VM" in MVVM)

Handles the business logic and state, communicating with the UI via Data Binding and Commands.

• PlayQuizViewModel: Manages the game loop, score tracking, and question navigation.
• Create/EditQuizViewModel: Handles the CRUD logic for managing the question bank.
• CategorySelectionViewModel: Logic for filtering and selecting quiz topics.

3. 🖥️ Views (The "V" in MVVM)

Pure XAML files responsible for the layout.

• CreateQuizView / EditQuizView: Forms for data entry.
• PlayQuizView: The interactive game interface.
• Value Converters: Uses NullOrEmptyToVisibilityConverter to dynamically control UI element visibility based on data state.

✨ Key Features

• Full CRUD System:
  • Create: Add new questions and quizzes.
  • Read: Load existing quizzes from storage.
  • Update: Edit typos or options in existing questions (EditQuizView).
  • Delete: Remove outdated content.
• Dynamic UI:
  • Real-time feedback during gameplay.
  • Smart visibility toggling using custom IValueConverter.
