.NET MAUI/Xamarin

.NET MAUI/Xamarin development creates mobile applications that share code across platforms. With our focus on the Microsoft Enterprise Platform, .NET MAUI/Xamarin is the Ballard Chalmers tool of choice for building mobile applications that are fully integrated with enterprise systems. This technology offers greatly reduced costs for cross-platform mobile development, together with a high level of C# code sharing between mobile apps and the systems they interface with.


Build your mobile application once and deploy anywhere.

With the .NET MAUI/Xamarin platform, we can create apps for iOS, Android, Windows, macOS, HoloLens, X-box and Tizen in C#. .NET MAUI/Xamarin developed apps all use the same language, APIs and data structures and share on average greater than 95% of code across all mobile development platforms. Making it a very cost-efficient form of development.

C# is also used to develop the server applications that mobile apps communicate with, resulting in the major benefit of having the same programming language and development platform in use across the full application development stack.

The benefits of building your app in .NET MAUI/Xamarin


Faster turnaround

Fewer bugs

Cost efficient

It’s Microsoft!

The development with Ballard Chalmers was straight forward with minimal user acceptance testing. Full credit goes to the developers and management of our development partner, who fully understood the requirements and delivered with remarkable speed. They made it a completely painless process and that gave us confidence that AppCan XP would be very successful.

Offline Working and SQLite

Developing mobile apps that work where there is no internet connection, and re-sync the data when back online, is essential for enterprise mobile applications.

In these cases, unless the data structures are extremely simple and can be stored in a data file, Ballard Chalmers will manage on-device data using an SQLite database. SQLite has the major advantage of being based on SQL which is known to most developers.

.Xamarin offers two ways to develop the UI for a mobile application and now there is the third option of .NET MAUI as well. Given the requirements of a mobile application, Ballard Chalmers can advise on which approach is the most suitable.


1. Forms:

  • This is based on XAML the standard for Windows Desktop application development
  • Offers very high levels of code compatibility between IOS, Android and Windows apps

2. iOS and Xamarin.Android:

  • Supports separate and totally native custom UI code for iOS and Android devices
  • Offers the opportunity for making the UI very device specific at the expense of having reduced code sharing. Only the non-UI elements will share code


  • Being multi-platform, .NET MAUI uses the latest .NET tech to build natively across Windows, macOS, iOS and Android
  • Uses a single C# codebase for all devices while maintaining the look and feel of the native platform
  • Use the power of Visual Studio to make beautiful apps

We can provide ongoing application support for custom software whether we built it or it is an existing system. Our support staff are fully qualified software engineers, not helpdesk staff. That means your support team will be very familiar with the technology used and be able to provide the expertise you need, when you need it.


Increase the capacity of your in-house team for custom software development with our expert team augmentation. Take our Microsoft Partner expertise and give your team the boost required to get your development completed. If you are tight for deadlines or taking on a larger project than normal in-house, this is a simple and fast solution.


With Xamarin end of support announced for May 2024, migration should be top of mind.

Broadly, the following steps need to be followed to migrate Xamarin.Forms apps to .NET MAUI:

  • Convert the projects from .NET Framework to .NET SDK style
  • Update namespaces
  • Update any incompatible NuGet packages
  • Address any breaking API changes
  • Run the converted app and verify functionality

Some Xamarin code will be able to make the upgrade, some will need abandoning and some re-writing. The process of sorting through the code and making these decisions will determine the best route to migration for each individual project.

Being very familiar with both Xamarin and .NET MAUI, the Ballard Chalmers engineers have the required expertise to skillfully migrate your apps from Xamarin to .NET MAUI when the time is right.
