What is .NET MAUI?

.NET Multi-platform App UI (MAUI) is a revolutionary framework that allows developers to create natively compiled applications across multiple platforms using a single codebase. By leveraging C# and XAML, developers can maintain productivity and maximize code reuse, creating efficient and effective user interfaces.

Setting Up Your Development Environment

Before you dive into coding, you’ll need to set up your development environment:

Install Visual Studio 2022: Ensure you have the latest version of Visual Studio with the .NET MAUI workload installed. This setup provides all the necessary tools to start your MAUI project.

Creating Your First MAUI App

Start a New Project: Open Visual Studio, and select “Create a new project.” Search for the .NET MAUI App template and select it.
Configure Your Project: Name your project and choose a suitable location for it on your system.
Select the Target Framework: It’s recommended to use the latest version of the .NET framework available in the template selection to ensure compatibility and access to the latest features.
Run Your App: After setting up your project, you can run it on various platforms. Whether you’re targeting iOS, Android, macOS, or Windows, Visual Studio provides a seamless experience for deploying and testing your application.

Exploring the “Hello World” Application

The default template comes with a simple counter application. You can interact with this app by pressing a button to increase a counter—perfect for understanding the basics of user interface and event handling in .NET MAUI.

Customizing Your App

As you get comfortable with the basics, start tweaking the app:

Modify the XAML: Change the layout, add new controls, and adjust the properties to customize the UI.
Adjust the Code-behind: Enhance the functionality by modifying the C# code. You can add new methods or change how the data is handled.
