What is C# development?
C# development is the building of software in C#, Microsoft's main programming language for the .NET platform. C# is unusually versatile: the same language builds secure web applications and APIs with ASP.NET Core, Windows and cross-platform desktop apps, cloud services on Azure, mobile apps with .NET MAUI, and even games and machine-learning features. That breadth is why so many businesses standardise on it.
A C# development company designs, builds, tests and maintains this software for you across whichever of those surfaces you need. Avaib has written C# since 2004, across more than 600 projects, so we can build new C# software or bring an ageing C# application up to date.
What can you build with C#?
A lot more than websites. In C# we build business systems and internal tools, back-end APIs and services, Windows desktop software in WPF and WinForms, cloud services on Azure, cross-platform desktop and mobile apps with .NET MAUI, and AI and machine-learning features with ML.NET and LLMs like OpenAI and Claude.
The advantage of C# is that one language, and with us one accountable team, can cover all of those surfaces, so the pieces share logic and standards instead of being built by separate vendors that never quite line up.
Can you build both a web app and a desktop app in C#?
Yes, and that is one of the strongest reasons to build in C#. We build web applications and APIs on ASP.NET Core, desktop software in WPF and WinForms, and cross-platform apps in .NET MAUI that run on Windows, macOS, iOS and Android from one codebase.
Because it is all C#, the shared business logic can be written once and reused across the web, desktop and mobile versions, so a single senior team delivers them consistently instead of three vendors building three subtly different products.
How much does C# development cost?
It depends on the scope, since a focused internal tool is very different from a system that runs your whole operation or one that spans web, desktop and cloud. That is why we scope the work clearly up front and give you a fixed, plain-language quote before any development starts, so there are no open-ended surprises.
Our senior C# engineers work at a cost-effective rate of around USD 25 per hour, the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, and AI-accelerated delivery helps get you there faster. After a short conversation we send you a free, no-obligation written estimate with a clear scope.
Is C# a good choice for a secure, enterprise-grade system?
C# on .NET is one of the most trusted foundations for secure, high-load business software, which is why it is common in finance, healthcare, government and other regulated sectors. It has mature security tooling, strong performance and long-term support from Microsoft.
We have built exactly this kind of system since 2004, designing to the security and compliance bar your environment requires, working with your existing authentication and infrastructure, and testing every slice through our dedicated QA department.
Do you provide dedicated C# developers or a fixed-price build?
Both. If your project is clearly defined, we scope it and deliver it for a fixed price. If you need ongoing capacity, we provide a dedicated team of senior C# specialists who work as an extension of yours, across whichever surfaces you need, and scale up or down as your priorities change.
Whichever model fits, the work is done by senior specialists under one accountable team, and you keep the code, data and documentation with no lock-in.
