MAUI Project and Solution Structure Details

.NET MAUI stands out in modern cross-platform application development. The MAUI project and solution structure offers great convenience to developers by providing a single codebase for different platforms. Correctly understanding the concepts of project and solution in MAUI is the key to creating a sustainable and readable code architecture.

What are MAUI Project and Solution?

A MAUI solution is the main container where you can manage your entire application and can host multiple projects. Typically, there is a single MAUI project and platform-specific projects (Android, iOS, Windows, macOS) within this solution. The MAUI project is the core that contains the main logic of your application, user interface, and functionality. In this structure, there is both shared code across platforms as well as platform-specific code.

MAUI Project File Structure

The typical MAUI project file structure is as follows:

MyMauiApp.sln        // Solution file
 └── MyMauiApp/       // Main MAUI Project
      ├── App.xaml         // Application entry point
      ├── MainPage.xaml    // Main page
      ├── Platforms/       // Platform-specific folder
      │    ├── Android/
      │    ├── iOS/
      │    ├── MacCatalyst/
      │    └── Windows/
      ├── Resources/       // Images, fonts, svg, etc.
      └── ...

Platform-Specific Code and File Management

In the MAUI project and solution structure, the shared C# code and XAML interface are located in the main project, while platform-specific settings and startup files for each platform are kept in the "Platforms" folder. For example, you can write your own sharing code or add a service specifically for Android as shown below:

// Platforms/Android/MainActivity.cs
namespace MyMauiApp.Platforms.Android
{
    [Activity(Label = "MyMauiApp", MainLauncher = true)]
    public class MainActivity : MauiAppCompatActivity
    {
    }
}

Adding a New Page

To add a new page to a MAUI project, you can do the following:

// MainPage.xaml.cs
view
public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
    }
}

Conclusion: The Importance of MAUI Project and Solution Structure

The MAUI project and solution structure offers great advantages to developers in terms of reusability, flexibility, and easy maintenance. With proper project structuring, you can gain a holistic experience without the need for separate developments for each platform. To fully benefit from .NET MAUI in your software development process, it is very critical to understand the structure of projects and solutions.
