Our .NET Development Process

1. Assessment & Architecture

We analyse your requirements (or existing codebase for migrations) and design an architecture that leverages the right .NET technologies. For migrations, we assess complexity, identify risks, and create a detailed migration plan.

2. Development

Using agile methodologies, we develop your application iteratively. You'll see working software regularly and can provide feedback throughout. We follow .NET best practices, including SOLID principles, clean architecture, and comprehensive testing.

3. Testing & Quality Assurance

Unit tests, integration tests, and end-to-end testing ensure your application works correctly. We use tools like xUnit, NUnit, and Playwright for comprehensive test coverage.

4. Deployment

We deploy to your preferred environment—Azure, AWS, on-premises, or hybrid. CI/CD pipelines automate the build and deployment process for reliable, repeatable releases.

5. Support & Maintenance

Post-launch support, bug fixes, performance optimisation, and feature development. We keep your .NET applications secure and up-to-date with framework updates.

Frequently Asked Questions

Should we use Blazor or a JavaScript framework?

Blazor is excellent for teams with C# expertise who want to use one language across the stack. It's particularly strong for internal applications, dashboards, and line-of-business apps. JavaScript frameworks like React may be better for highly interactive consumer apps or when you need the broader JavaScript ecosystem. We can help you evaluate the best choice for your specific needs.

Is .NET MAUI ready for production?

Yes, .NET MAUI is production-ready and is Microsoft's recommended path for cross-platform .NET development. It's the natural evolution of Xamarin.Forms with significant improvements. Major companies are using MAUI in production, and Microsoft provides long-term support.

How difficult is migrating from Xamarin to MAUI?

Migration complexity varies based on your app. Simple apps using standard Xamarin.Forms controls can often migrate smoothly with the .NET Upgrade Assistant. Apps with heavy custom renderers, platform-specific code, or third-party libraries may require more work. We assess each project individually and provide realistic migration plans.

Should we migrate our .NET Framework application?

.NET Framework is in maintenance mode—Microsoft won't add new features. Modern .NET offers better performance, cross-platform support, containerisation, and access to the latest C# features. If your application is actively developed or has a long future, migration is typically worthwhile. We can assess your specific situation and ROI.

Can you work with our existing .NET codebase?

Absolutely. We frequently join existing projects, whether to add features, improve performance, fix issues, or help with modernisation. We'll review your codebase, understand your architecture, and integrate with your team's workflows and practices.

What's the difference between .NET for Android and .NET MAUI?

.NET for Android provides direct access to Android APIs using C#—you write Android-specific UI code. .NET MAUI is a cross-platform framework where you write shared UI code that runs on Android, iOS, Windows, and Mac. Choose .NET for Android when you need maximum platform control; choose MAUI when you want code sharing across platforms.
