Introduction to Dot Net MAUI

Dot Net MAUI (Multi-platform App UI) is the latest evolution of Microsoft's cross-platform application development framework. It is a modern and unified approach to building mobile, desktop, and web applications for various platforms such as Android, iOS, macOS, and Windows. It was first announced at the virtual Microsoft Build conference in May 2020 and is expected to be released in November 2021.

What sets Dot Net MAUI apart from its predecessor, Xamarin.Forms, is that it combines the power of .NET with the flexibility of native user interfaces. This means developers can use their existing C# skills and codebase to create fully native apps for multiple platforms.

Key Features of Dot Net MAUI:

  • Cross-platform support: With Dot Net MAUI, you can build apps that can run on Android, iOS, macOS, and Windows devices.
  • Single codebase: Developers only need to write one codebase for all supported platforms
  • Native performance: The apps built with Dot Net MAUI have a native look and feel as they are compiled into platform-specific builds.
  • XAML-based UI: Along with C#, developers can also use XAML to design beautiful user interfaces for their apps.
  • Unified API surface: With a single API surface across all platforms, developers can easily access device-specific features without having to write separate code for each platform.
  • Third-party library integration: Developers can utilize popular third-party libraries like SQLite or ReactiveUI within their Dot Net MAUI applications.

What is Dot Net MAUI?

Dot Net MAUI (Multi-platform App UI) is an open-source cross-platform framework for building native mobile and desktop applications. It is the evolution of Xamarin.Forms, a popular framework for developing cross-platform apps using C# and .NET. MAUI was announced by Microsoft at the Build 2020 conference as part of their .NET 6 release.

At its core, Dot Net MAUI uses the same principles as Xamarin.Forms, allowing developers to write code once and deploy it across multiple platforms such as iOS, Android, Windows, macOS, and more. This significantly reduces development time and effort compared to building separate apps for each platform.

One of the main benefits of MAUI is that it leverages the power of .NET 6, which brings several improvements to the development experience. These include a unified architecture for both client-side and server-side code, improved performance through ahead-of-time (AOT) compilation, enhanced support for modern language features such as nullable reference types and source generators.

Another significant improvement with MAUI is its support for single-project development. In previous versions of Xamarin.Forms, developers had to maintain separate projects for each platform they wanted to target. With MAUI's single-project structure, all app logic and resources can be contained in one place, making it easier to manage and maintain.

MAUI also introduces new features such as Hot Reload, which allows developers to make changes to their code while the app is running without having to rebuild or redeploy it. This greatly speeds up the development process and provides instant feedback.

Benefits of Using Dot Net MAUI

Dot Net MAUI is the latest cross-platform mobile development framework from Microsoft, built on top of .NET and Xamarin. It combines the strengths of both to provide a powerful, efficient, and user-friendly solution for building high-quality mobile applications. In this section, we will discuss some of the key benefits that come with using Dot Net MAUI.

  • Native User Experience: One of the biggest advantages of using Dot Net MAUI is its ability to create truly native apps for different platforms like iOS, Android, and Windows. This means that your app will have full access to platform-specific features and APIs, resulting in a seamless and consistent user experience across all devices.
  • Code Reusability: With Dot Net MAUI, you can write your code once and use it across all platforms without any modifications. This not only saves time but also reduces the effort required to maintain multiple codebases for different platforms. Moreover, as it is built on .NET technology, developers familiar with C# can easily transition into developing apps with Dot Net MAUI.
  • Improved Performance: As mentioned earlier, Dot Net MAUI allows for creating native apps, which translates into better performance compared to hybrid or web-based solutions. By using platform-specific APIs and features, you can optimize your app's performance based on each platform's unique capabilities.
  • Enhanced UI Capabilities: The new user interface (UI) system in Dot Net MAUI offers a wide range of customizable controls and layouts that allow you to create stunning user interfaces. Whether you need a simple interface or a complex one, Dot Net MAUI provides the tools and flexibility to bring your design ideas to life.

Understanding the Basics: C#, XAML, and .NET MAUI SDK

C#, XAML, and the .NET MAUI SDK are the three foundational components of creating cross-platform applications using Dot Net MAUI. In this section, we will delve into the basics of each of these technologies and their role in developing robust and efficient applications.

C# (C-Sharp)

C# (pronounced as C-Sharp) is a modern, object-oriented programming language developed by Microsoft. It is one of the primary languages used for building applications on the .NET platform. With its simple syntax and powerful features like garbage collection, LINQ, and asynchronous programming support, C# has become a popular choice for developers worldwide.

XAML (eXtensible Application Markup Language)

XAML (eXtensible Application Markup Language) is an XML-based markup language used for designing user interfaces in .NET applications. It allows developers to separate the design elements from code-behind logic, making it easier to maintain and update UI elements without affecting the application's functionality. XAML provides a declarative way of defining interfaces that can be easily understood by both designers and developers.


The .NET Multi-platform App UI (MAUI) SDK is an evolution of Xamarin.Forms that enables developers to build native cross-platform apps with a single codebase using familiar tools like C# and XAML. The MAUI SDK simplifies mobile development by providing a unified API surface across multiple platforms like Android, iOS, macOS, Windows, etc., allowing developers to leverage their existing skills to create high-quality apps.

One of the significant advantages of using Dot Net MAUI over traditional approaches like writing platform-specific code is the ability to maintain a single codebase. With Dot Net MAUI, you can develop and maintain one codebase for all supported platforms, which significantly reduces development time and effort.
