Description

Introduction
Xamarin.Forms is a powerful framework for building cross-platform mobile applications using a single codebase in C#. It enables developers to create native-like user interfaces for iOS, Android, and Windows while sharing most of the business logic and UI code. This training focuses on designing responsive layouts and styling techniques to ensure that applications look polished and function seamlessly across multiple devices and screen sizes. Participants will learn how to leverage Xamarin.Forms layouts, controls, styles, and adaptive design principles to create visually appealing, user-friendly, and maintainable mobile applications.

Prerequisites
Basic knowledge of C# and .NET framework
Familiarity with object-oriented programming concepts
Understanding of Xamarin.Forms fundamentals and XAML syntax
Experience with Visual Studio and mobile app development environment setup
Basic understanding of MVVM (Model-View-ViewModel) pattern
Knowledge of device form factors, screen resolutions, and platform differences
