Getting Started with .NET MAUI: Mobile Development Using C#

Introduction

Are you ready to dive into the world of cross-platform mobile development with C#? Look no further! .NET MAUI (Multi-platform App UI) is here to simplify the process of building native mobile and desktop apps with a single codebase. In this comprehensive guide, we'll walk you through getting started with .NET MAUI and show you how to create your first app.

What is .NET MAUI?

.NET MAUI is an evolution of Xamarin.Forms, designed to provide a more modern and streamlined development experience. It allows developers to write code once and run it on multiple platforms, including Android, iOS, macOS, and Windows. This powerful framework ensures that you can deliver a consistent and native user experience across all devices.

Why Choose .NET MAUI for Mobile Development?

• Single Codebase: Write your app once and run it anywhere.
• Native Performance: Get the performance benefits of native apps.
• Productivity: Utilize the power of C# and .NET to speed up development.
• Modern UI: Build beautiful and responsive UIs with XAML and .NET.

Setting Up Your Development Environment

To start developing with .NET MAUI, you'll need to set up your development environment. Follow these steps:

1. Install Visual Studio 2022:

   • Download and install Visual Studio 2022.
   • During installation, select the Mobile development with .NET workload.

2. Create a New .NET MAUI Project:

   • Open Visual Studio 2022.
   • Select Create a new project.
   • Choose .NET MAUI App template.
   • Click Next, then configure your project name and location, and click Create.

Understanding the Project Structure

When you create a .NET MAUI project, you'll notice several key components:

• MainPage.xaml and MainPage.xaml.cs: These files define the main user interface (UI) of your application.
• App.xaml and App.xaml.cs: These files manage global styles and application-level resources.
• Platforms folder: Contains platform-specific code and resources for Android, iOS, macOS, and Windows.

Building Your First .NET MAUI Application

Let's create a simple app with a button that displays a message when clicked.

1. Open MainPage.xaml:

   xml
   <?xml version="1.0" encoding="utf-8" ?>
   <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
                xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                x:Class="MyMauiApp.MainPage">
   
       <StackLayout Padding="10">
           <Label Text="Welcome to .NET MAUI!"
                  VerticalOptions="CenterAndExpand" 
                  HorizontalOptions="CenterAndExpand" />
   
           <Button Text="Click Me" 
                   VerticalOptions="CenterAndExpand" 
                   HorizontalOptions="CenterAndExpand"
                   Clicked="OnButtonClicked"/>
       </StackLayout>
   
   </ContentPage>
   

2. Open MainPage.xaml.cs:

   csharp
   using Microsoft.Maui.Controls;
   
   namespace MyMauiApp
   {
       public partial class MainPage : ContentPage
       {
           public MainPage()
           {
               InitializeComponent();
           }
   
           private void OnButtonClicked(object sender, EventArgs e)
           {
               DisplayAlert("Clicked!", "You clicked the button.", "OK");
           }
       }
   }
   

Running Your Application

1. Select a Target Device:

   • In Visual Studio, use the device selector to choose an emulator or a connected device.

2. Build and Run:

   • Click the Run button (green arrow) to build and deploy your app.
