Chapter 1: Getting Started with .NET MAUI
What is .NET MAUI?
.NET Multi-platform App UI (MAUI) is a cross-platform framework developed by Microsoft, designed to build native applications for Android, iOS, macOS, and Windows using a single codebase. It is the evolution of Xamarin.Forms, providing a unified approach to UI and application development within the .NET ecosystem.
.NET MAUI allows developers to write applications in C# and XAML while ensuring performance and native API access across different platforms. Unlike traditional mobile development, where separate codebases for each platform were required, .NET MAUI streamlines the process by offering a single project structure.
Key Highlights:
- Single Codebase: Write once and deploy to multiple platforms.
- Unified UI Framework: Develop with a consistent UI design across platforms.
- Performance Optimizations: Native compilation and improved rendering.
- Seamless Integration with .NET 6+: Leverages the latest .NET features.
- Access to Native APIs: Use platform-specific APIs when needed.
Features and Benefits of .NET MAUI
.NET MAUI extends the capabilities of Xamarin.Forms by providing enhanced features and simplifying app development. Here are some of its key benefits:
- Cross-Platform Compatibility: Build applications that run on multiple platforms without writing platform-specific code.
- Hot Reload Support: See changes in real-time without recompiling the entire application.
- Native Performance: Ensures optimized performance across different devices.
- Unified Project Structure: Maintain a single project for all platforms.
- Support for MVU and MVVM Patterns: Choose the preferred design pattern for better code maintainability.
- Deep Integration with Visual Studio: Provides tools, debugging support, and templates for streamlined development.
- Access to Native APIs: Utilize device features like camera, GPS, and notifications.
.NET MAUI vs Xamarin.Forms
| Feature |

.NET MAUI |
| Codebase Structure |
Multiple projects per platform |
Single project for all platforms |
| Performance |

.NET MAUI replaces the traditional renderers in Xamarin.Forms with handlers, improving performance and flexibility. It also simplifies project setup by consolidating multiple platform-specific projects into a single unified project.
Understanding Cross-Platform Development
Cross-platform development enables developers to create software that runs on multiple operating systems using a shared codebase. This approach offers several advantages, including:
- Cost Efficiency: A single development team can target multiple platforms, reducing development costs.
- Code Reusability: The majority of the application logic can be shared, minimizing redundant code.
- Faster Time-to-Market: With a unified codebase, development cycles are shorter, allowing faster deployment.
- Consistent User Experience: UI components and behaviors remain uniform across platforms.
Approaches to Cross-Platform Development
There are different approaches to building cross-platform applications:
- Hybrid Frameworks: Use a single language (JavaScript, Dart) but rely on a bridge to interact with native components. (e.g., React Native, Flutter)
- Progressive Web Apps (PWAs): Web applications that function similarly to native apps but run in browsers.
- Native Cross-Platform Frameworks: Allow developers to write native applications using a single programming language (C#) while providing direct access to native APIs. (.NET MAUI, Xamarin)
.NET MAUI follows the third approach, ensuring both performance and flexibility by leveraging the native capabilities of each platform.
Tools and Prerequisites
Before diving into .NET MAUI development, ensure you have the necessary tools installed:
| Tool |
Description |
| Visual Studio 2022 |
Provides templates and debugging tools for .NET MAUI. Install the .NET MAUI workload during setup. |
| .NET SDK (6.0 or later) |
Required to run and build .NET MAUI applications. Download from Microsoft .NET. |
| Android and iOS Emulators |
For Android, install SDK & configure an emulator in Visual Studio. For iOS, use macOS & Xcode. |
| Windows Subsystem for Linux (Optional) |
Useful for cross-platform applications needing backend services. |
| Git and Version Control |
Use GitHub or Azure DevOps for efficient code management. |
Example: Setting Up Your First .NET MAUI Project
Follow these steps to create a new .NET MAUI project:
- Open Visual Studio 2022.
- Click on Create a new project.
- Select .NET MAUI App and click Next.
- Configure your project name and location.
- Click Create.
- Run the application using the Android Emulator or Windows Machine.
Once the setup is complete, you will see a default .NET MAUI template with a simple interface. This confirms that your development environment is ready!
Conclusion
This chapter introduced .NET MAUI, its features, benefits, and how it compares to Xamarin.Forms. We also discussed cross-platform development and the tools required to get started.
In the next chapter, we will explore the architecture of .NET MAUI and how to build user interfaces efficiently. Stay tuned for hands-on coding examples!
