FAQ

FAQs About Xamarin App Development Services

 

Xamarin development typically costs 40-60% less than building separate native iOS and Android apps. With up to 90% code sharing, you’re essentially getting two apps for the price of one. We provide detailed, transparent estimates after understanding your requirements in our free consultation.

 

 

Yes. Xamarin compiles to native ARM code and achieves performance equivalent to Swift and Kotlin. Unlike JavaScript-based frameworks that use bridges, Xamarin code runs natively. Companies like UPS, Alaska Airlines, and Olo trust Xamarin for performance-critical applications.

 

 

Xamarin.Forms allows sharing both UI and business logic (up to 96% code sharing) using a single XAML-based interface. Xamarin.Native (Xamarin.iOS/Xamarin.Android) shares business logic but uses platform-specific UI code for pixel-perfect native interfaces. We recommend the best approach based on your requirements.

 

 

Microsoft has evolved Xamarin into .NET MAUI (Multi-platform App UI), which is the successor framework. Existing Xamarin apps continue to work, and we provide migration services to .NET MAUI. New projects can start with either technology depending on your timeline and requirements.

 

 

Absolutely. This is one of Xamarin’s biggest advantages. If your team knows C# and .NET, they can become productive with Xamarin immediately. The business logic, patterns (MVVM), and tools (Visual Studio) are familiar. We can also train your team on mobile-specific best practices.

 

 

Development timelines depend on complexity. A basic MVP can be ready in 2-3 months, while feature-rich enterprise apps typically take 4-6 months. Xamarin’s code sharing accelerates development by 30-50% compared to building separate native apps sequentially.

 

 

Yes, Xamarin has first-class Azure integration. We routinely connect Xamarin apps with Azure App Services for backends, Azure AD for authentication, Notification Hubs for push notifications, Cosmos DB for data, and Cognitive Services for AI capabilities. This is a key advantage for Microsoft-centric organizations.

 

 

Yes, we offer comprehensive post-launch support including bug fixes, OS compatibility updates, feature enhancements, and performance optimization. We also provide .NET MAUI migration services when you’re ready to upgrade your Xamarin apps.
