Cross-platform development is becoming increasingly essential as the demand for applications that run on multiple devices grows. Microsoft’s .NET Multi-platform App UI (MAUI) is a powerful framework web designed to streamline the development process by allowing developers to create applications for Android, iOS, macOS, and Windows from a single codebase. This blog will delve into the .NET MAUI for Cross-Platform Development. Are you looking to advance your career in Dot Net? Get started today with the Dot Net Training in Chennai from FITA Academy!

What is .NET MAUI?

.NET Multi-platform App UI (MAUI) is a framework that enables web developers to build native applications for Android, iOS, macOS, and Windows using C# and XAML. It is part of the .NET ecosystem and leverages the capabilities of .NET 6/7, providing a modern and flexible development environment. MAUI abstracts the platform-specific details and offers a unified API to access native controls and services, making it easier to write cross-platform code.

Key Features of .NET MAUI

  • Single Project Structure: MAUI consolidates all platform-specific projects into a single project, simplifying project management and configuration.
  • Hot Reload: Supports XAML and .NET Hot Reload, allowing web developers to see the changes in real-time without restarting the application.
  • Cross-Platform APIs: Provides consistent APIs for accessing device features such as sensors, cameras, and file systems.
  • MVU Pattern: Introduces the Model-View-Update (MVU) pattern, enabling a more reactive approach to building user interfaces.
  • Blazor Integration: Allows using Blazor components in MAUI applications, combining web and native UI development.

Getting Started with .NET MAUI


Before diving into .NET MAUI, ensure you have the following prerequisites:

  • Visual Studio 2022: Make sure that you have the .net latest version of Visual Studio 2022 with the .NET MAUI workload installed.
  • .NET 6/7 SDK: Install the .NET SDK to build and run MAUI applications.
  • Emulators/Simulators: Set up Android and iOS emulators or simulators for testing your applications. Learn all the Dot Net Development and Become a Dot Net Developer. Enroll in our Dot Net Online Course.

Creating Your First .NET MAUI Project

  1. Open Visual Studio 2022: Start Visual Studio and select “Create a new project”.
  2. Choose MAUI App: Search for “MAUI” and select the “.NET MAUI App” template.
  3. Configure the Project: Enter your project name, location, and solution name, then click “Create”.

Project Structure

The .NET MAUI project structure consists of a single project that includes platform-specific folders (Platforms) and shared code. The MainPage.xaml and MainPage.xaml.cs files are where you define your user interface and behavior.

Building the User Interface

Define the UI in MainPage.xaml using XAML, a declarative language for designing user interfaces.

<ContentPage xmlns=””




        <Label Text=”Welcome to .NET MAUI!”


               HorizontalOptions=”CenterAndExpand” />

        <Button Text=”Click Me” 



                Clicked=”OnButtonClicked” />



In MainPage.xaml.cs, handle the button click event:

public partial class MainPage : ContentPage


    public MainPage()




    private void OnButtonClicked(object sender, EventArgs e)


        DisplayAlert(“Alert”, “Button clicked!”, “OK”);



Running the Application

Run the application by selecting the target platform (Android, iOS, macOS, or Windows) and clicking the “Run” button. Visual Studio will build and deploy the application to the selected emulator or device.

.NET MAUI is a game-changer for cross-platform development, offering a unified approach to building applications for multiple devices. By providing a single codebase and consistent APIs, MAUI simplifies the development process, enhances code reusability, and ensures a consistent user experience. Whether you are a seasoned Xamarin developer or new to cross-platform development, .NET MAUI is a powerful framework worth exploring. Start building your first .NET MAUI application today and experience the benefits of streamlined cross-platform development. Looking for a career in Dot Net Developer?
