A Beginner’s Guide to Building Mobile Applications with .NET Maui

A guide through building your first application using .NET MAUI.

Mobile applications have become indispensable parts of our daily lives. There is an app for almost everything. Social networking, productivity, project management, and BetNow betting apps make it possible to complete tasks and enjoy our favorite hobbies with a couple of finger taps, helping make our everyday lives easier and more streamlined. You have come to the right place if you are a beginner looking to dive into the world of mobile app development because we are about to guide you through building your first application using .NET MAUI.

What is .NET MAUI?

.NET Multi-platform App IU (MAUI) is an open-source framework developed by Microsoft that allows users to create native cross-platform applications for Android, iOS, macOS, and Windows using a single codebase. With .NET MAUI, developers can write their application code once and deploy it natively across multiple platforms, eliminating the need to maintain separate codebases for each platform. 

Having an application available across the most popular platforms is important in an age where consumers often own several devices. Not having several codebases speeds up development and helps streamline maintenance and updates.

.NET MAUI’s user-interface toolkit is another reason for its popularity among developers. It enables developers to create eye-catching, responsive user interfaces using XAML (eXtensible Application Markup Language), similar to HTML. Developers can create unique, bespoke designs and user experiences for users regardless of the devices they use to access the app.

Additionally, .NET MAUI offers seamless access to device-specific features, such as accessing a device’s camera or one of a myriad of sensors, enabling developers to create feature-rich and immersive mobile applications.

Getting Started With .NET MAUI

You need to set up your development environment before you can begin developing your application. Thankfully, this simple process only involves a handful of steps.

First, download and install Visual Studio from the official website. Visual Studio is Microsoft’s integrated development environment, which is super easy to grasp. Next, install the .NET MAUI workload in Visual Studio using the Visual Studio Installer, following any on-screen prompts that come your way. Lastly, set up an Android or iOS emulator to test your application. These emulators mimic mobile devices, allowing you to see what the app looks like and how it performs without installing it onto an Android or iOS-powered device.

Create Your First Project

Creating a new .NET MAUI project is another simple task. Open Visual Studio and choose to create a new project. Select .NET MAUI from the list of project templates, choose a name and location for your project, and click create. Visual Studio will then whir away and generate a basic .NET MAUI project structure for you. The project structure includes many necessary files and folders. Some of those files and folders include:

  • App.xaml: This crucial file contains the application’s main entry point and defines the global application resources.
  • MainPage.xaml: You’ll design your application’s layout and add controls here because it is the main user interface of your app.
  • ViewModels: Click here to see your app’s view models. These act as an intermediary between your user interface and business logic.
  • Services: As its name suggests, services is where you can define any services that your app requires, such as networking or data access.

Let’s Get Building Your User Interface

Designing your app’s user interface is one of the most fun parts of app development. You must also perfect this stage because user experience is everything. If you get it wrong, the end user will drop your app like a hot potato.

Open the MainPage.xaml files and add user interface controls like buttons, text boxes, and labels. You can write XAML code directly or use Visual Studio’s intuitive drag-and-drop interface.

Add Some Functionality

Having an application that is pleasing to the eye is one thing, but the best apps are crammed full of functionality. If you have a button that needs to perform a specific task when the user clicks it, you can handle the button’s click event in your code-behind file and write the necessary logic there. Writing C# code-binding for your XAML pages allows you to do this.

Test, Debug, and Test Again

Testing and debugging are as important, if not more so, than developing your app. App users demand a smooth and reliable experience regardless of their platform or device. If a user encounters a bug, even a seemingly minor bug, they will often delete your app and never redownload it.

Thankfully, Visual Studio provides powerful debugging tools that enable you to step through your code, inspect variables, and set breakpoints in real time. Testing your app on different devices, operating systems, and screen sizes is essential to ensure compatibility and responsiveness. You want users to have the same experience, and all promised features to work as intended regardless of their phone’s orientation, screen size, or operating system build. Android and iOS emulators allow you to simulate different device configurations, so use them!

Publish Your App

It is now time to share your bug-free app with the world! .NET MAUI supports publishing to various app stores, including the Apple App Store and Google Play Store. Each app store has strict guidelines for distributing and packaging your app, and it may be necessary to create a developer account and go through a review process before your app is published. Be aware that the Apple App Store and Google Play Store review apps again if any updates are made. This can make your app unavailable to download until the review process is complete.

Conclusion

Hopefully, you have just finished developing and publishing the first of many apps using .NET MAUI. This guide only scratched the surface and the basics of app development. Now, it is time for you to go out there and take your development to the next stage. Continue learning, experimenting, and building creative and innovative apps that help enrich the lives of mobile users worldwide.
