Microsoft's New Multi-platform App UI (.NET MAUI) - The Future of cross-platform app Development

Microsoft's New Multi-platform App UI (.NET MAUI) - The Future of cross-platform app Development


The future of cross-platform app development is here. The Microsoft .NET Multi-Platform UI(MAUI) framework allows developers to build cross-platform applications that run on Windows, MacOS, iOS, Android, and Linux. Microsoft's Multi-platform App UI (MAUI) Framework is a set of tools and libraries that allow you to build modern, multi-platform applications using C# or F#.

Microsoft has made many headlines over the last couple of years with its efforts to support other platforms besides the Microsoft Windows Platform, including Android, iOS, Mac, and even Ubuntu Linux. The MAUI Framework lets you write code once and run it anywhere. It is based on the Microsoft Reactive Extensions (Rx) framework and was developed to help developers create high-quality and fast user experiences. This framework uses the same code base to easily port your application from one platform to another with minimal effort. You can use it to write applications for any platform where .NET Core supports a GUI toolkit or widget set.

What is Cross-platform application development?

Cross-platform application development is a process of developing software applications that can run on multiple platforms. The term cross-platform is used to describe computer programs that are designed to run on a variety of computing platforms. It also refers to the ability of a single OS-level operating system to support multiple hardware platforms.

Building multi-platform applications is a challenge. You have to deal with many things, and building an app that works on all platforms takes work. This is why Microsoft has created this new framework. The Multi-platform App UI (MAUI) framework allows us to create our own UI components and use them on any platform we want.

Why use MAUI?

The main reason why you would want to use .NET MAUI is that it gives you the ability to write one code base that can run on multiple platforms without any major modifications needed. This means that if updates or changes are being made to the UI in one platform, these changes can be applied across all other platforms without making any other changes. This helps make maintenance easier as well as lower costs associated with having separate teams working on different platforms.

The MAUI framework gives you access to native performance and quality in each supported platform. You can maintain quality when targeting multiple platforms with your application. You can rest assured that your application will look and perform great on all platforms without compromising on any of them!

You might think that this sounds a lot like React Native, but what makes .NET MAUI different from other cross-platform frameworks is that it uses actual .NET code rather than JavaScript. This means you get full access to all the power and flexibility of C# or F# without any of the performance or quality issues associated with other technologies like JavaScript, HTML5, or CSS3.


There are many reasons why performance matters to developers. First and foremost, it’s important because users don’t want to wait for their apps to load or responds lowly when they are interacting with them. They expect applications to be fast, responsive, and work without problems across different devices and platforms. Secondly, application performance metrics are increasingly being used as an indicator of quality by both customers and developers, so it makes sense from a business perspective to ensure that your application performs well across all devices and platforms. Thirdly, if your application performs poorly, then your users will lose trust in your brand and may stop using it altogether, which could damage your reputation with them in addition to losing potential revenue opportunities through negative customer reviews left on different application review sites.

What is different about MAUI?

MAUI is the evolution of Xamarin. Forms, the mobile UI framework for .NET developers. Xamarin was acquired by Microsoft and is now a part of the .NET Foundation. MAUI is built on top of Xamarin. Forms, but removes some of its limitations to make it easier to build high-quality native apps.

The MAUI framework contains many different components designed to help make it easy for developers to create high-quality apps using C#, F#, or VB while still taking advantage of all the latest features available in each platform, such as gestures, animations, and push notifications, etc.

Prerequisites for using MAUI

To start building apps with MAUI, you need the following:

  • Visual Studio 2019 or 2022 version installed on your computer (preferably Visual Studio Enterprise).
  • At least one version of .NET Core 2.1 SDK installed on your machine.

Here are some of the features that MAUI provides:

  • XAML support: MAUI supports XAML files and HTML files, so you can easily use existing XAML or HTML code in MAUI projects without any issues.
  • Cross-platform support for Android, iOS, and Windows. This means you can use the same codebase to build apps for these platforms with minimal changes in the code.
  • Many UI controls and layouts are available out of the box. This includes standard controls like buttons, checkboxes, textboxes, etc., and custom layouts such as list views, maps, etc. It also provides components for standard functionality like grid views, navigation bars, and dropdown lists.
  • Easy integration with other libraries using NuGet packages. You can use third-party libraries like jQuery or Bootstrap with little or no modification in your codebase.
  • A consistent API across all platforms and automatic generation of APIs from UIs.
  • MAUI is fast and easy to use.
  • MAUI Comes with rich data binding support with declarative expressions and no code-behind needed.
  • It supports the MVVM design pattern architecture with automatic events wiring by default. No manual event wiring is required.

MAUI has been designed to be highly portable across any platform or device from the ground up. It’s easy to learn, use and maintain, with minimal code and a familiar programming model.

Benefits of using MAUI. Microsoft’s Multi-platform App UI (.NET MAUI)

  1. It allows you to write code once and run it on multiple platforms.
  2. It provides a portable layer that can be used to access native features from each platform.
  3. It has a built-in layout engine that uses a declarative syntax similar to HTML5markup language (HTML). This makes it easier for designers to create layouts without writing any code.
  4. Higher productivity with less code required. This means easy migration to new versions of the same app without needing to rewrite it altogether.
  5. It supports responsive design and easily adapts layouts depending on screen size or orientation (landscape or portrait).
  6. Users of the MAUI UI framework receive great support from the Microsoft team.

The main benefit of using the .NET MAU framework is that it reduces the cost and time needed to develop an application. By creating a single codebase and then compiling it for different platforms, developers can avoid having to write separate codebases for each platform they want to support. .NET MAU also makes it easier for developers because they no longer need to learn how different operating systems work or how their APIs differ from one another. Instead, they can focus on writing code that works across all platforms without worrying about which the user’s device is using OS or API at any given time.

In addition to saving time and money, using the NET MAU framework will give you access to more users because it allows your app to run on multiple devices.

The difference between .NET MAUI and Xamarin. Forms

On the surface, .NET MAUI and Xamarin. Forms appear to be very similar. Both are cross-platform mobile development frameworks that allow you to build native apps using C#. However, they're fundamentally different in how they approach the problem of building cross-platform apps.

The most significant difference between the two is that Xamarin Forms is based on the Microsoft XAML framework, and .NET MAUI is based on the native Android and iOS frameworks. This means that Xamarin Forms use a lot of code to translate business logic into native code, while .NET MAUI only needs to translate user interface code into native code.

Xamarin Forms is an excellent tool for building mobile applications, but it was never intended to be used as the only UI framework on all platforms. Xamarin Forms is based on the PCL (Portable Class Library) technology, which means it has to be compiled separately for each platform.

The main issue with this approach is that you have to write a lot of boilerplate code in order to implement basic things like layout management and interaction with native APIs. That's why Microsoft decided to create MAUI, a new cross-platform UI framework for .NET Core that uses native controls where possible abstracts them when needed, and provides powerful features like layout management and data binding out of the box.

Migrating from Xamarin Forms to .NET MAUI

Migrating to .NET MAUI is easy because it's built on top of existing platforms, but there are some differences that you need to take into account:

The most important difference is in how you handle data binding. In Xamarin Forms, you can bind to any property or field, including custom types such as DTO objects or classes with virtual properties (like Observable Collection). This also means you can use bindings inside your view models, not just in views. However, in .NET MAUI, this isn't possible; instead, you should use Rx Swift or MVVM. You can still bind to custom types if they implement NS Coding (like UI Color), but this means that you can't bind directly to the object itself instead.

The main advantage of choosing.NET MAUI over Xamarin Forms is that we can now use C# instead of Mono for developing cross-platform mobile apps. The major benefit of this is that our code will be much easier to read and maintain. They are migrating from Xamarin. Forms to .NET MAUI is pretty straightforward as both frameworks share many common concepts (such as layouts, data binding, etc.). It's easy to build beautiful, native apps with MAUI. The framework provides a set of controls that automatically adapt themselves to look like their native counterparts on Android or iOS. You can also create custom controls that look exactly like you want them to without having to worry about underlying platform APIs.

What is the Future of Cross-platform Development?

The future of App development is bright, and it will only get better. NET MAU is here to help you develop the best Cross-platform apps possible by providing you with the tools you need to succeed.

Microsoft's dedication to the .NETMAU platform has shown its willingness to invest heavily in new features and frameworks that help developers build better apps faster. The company has also made significant investments in improving the overall experience for users, including adding support for Progressive Web Apps (PWAs) and making it easier for developers to run their applications as a Service (SAAS).

While there are many challenges facing developers, including a lack of support for cross-platform codebases, there are still plenty of reasons why it should be high up your list when considering which platforms you should develop.

The major factor that will continue to influence the future growth of cross-platform application development will be the growing trend for businesses to embrace digital technologies in their operations. This trend will increase demand for cross-platform tools, which will offer greater flexibility and scalability than traditional software design and development methodologies.

The demand for cross-platform development is growing at an incredible rate. There are many reasons for this, but the most important reason is that companies want their products to work one very device, regardless of operating system or platform. This reduces the need for multiple applications and makes it easier for users to find your product across multiple platforms.

The problem with cross-platform development is that it has been traditionally difficult to do well. Many developers have tried to create cross-platform applications before but have often failed due to the complexity of the task. The solution was usually to create separate applications for each platform which defeats the purpose of trying to develop a single application in the first place. That’s why the Microsoft team created .NET MAU, a brand-new technology that allows you to build one application that runs natively on all major platforms (iOS, Android, Windows Phone 8 & 10) without compromising on features or functionality!


To conclude, the new MAUI Unified Interface (UI) will address many of the issues developers have complained about when it comes to implementing cross-platform application development. It will also give developers an easy-to-use platform to implement their apps for various targeted OS platforms.

The development of cross-platform application UI on NET is not just a phenomenon but a long-term trend. The release of this new product indicates that the enterprise development platform: NET's global influence has reached an unprecedented scale. Microsoft will continue to play global engineering and innovation of products, leading the entire industry.

In a world where mobile apps are becoming the norm, companies need to evaluate their options for cross-platform development. As we have seen here, a native multi-platform app can potentially solve this growing problem. Although .NET MAUI is still being improved to offer better solutions in the near future, it does hold promising potential for developers looking to keep their applications responsive and intuitive for users.
