WPF utilizes XAML (Extensible Application Markup Language) to define the user interface, separating the UI design from the code behind it.

Event Handling and User Interaction

Event handling is crucial in Windows applications. User actions, such as clicking a button or entering text, trigger events. The application’s code responds to these events by executing corresponding methods, enabling user interaction. This responsiveness is key to creating interactive applications. Examples include handling mouse clicks, key presses, and form resizing events.

Structure of a Basic Windows Application Project

A basic Windows application project typically comprises a main form, controls like buttons and text boxes, and code that defines the application’s logic. The project structure reflects the modularity and organization of the code. The code behind the form (e.g., the `Form1.cs` file) typically contains the event handlers and logic to respond to user interactions.

Differences Between Console and GUI Applications

Console applications rely on text-based input and output, while GUI applications utilize graphical elements for user interaction. GUI applications provide a more user-friendly experience, enabling a wider range of functionalities and user input methods.
