Migration of Industrial Pump Selection & Configuration App from Xamarin Native to MAUI

A legacy system transformation for a European engineering software provider

Xamarin Native to MAUI Migration of a Pump Config App

A European industrial software company specializing in pump configuration solutions was facing significant performance issues and support limitations with its existing mobile app. To address these challenges, they partnered with Rishabh Software to initiate a Xamarin Native to MAUI migration. This strategic move aimed to modernize the app, enhance UX and retain their tightly integrated backend architecture without disrupting existing workflows.

Key Features

Rishabh Software modernized the outdated mobile app into a robust, cross-platform solution using .NET MAUI. The redesigned application delivers improved responsiveness, streamlined workflows, and easier maintainability.

Unified Cross-Platform Interface

Our team rebuilt the app in .NET MAUI to enable shared codebase for Android and iOS. This reduced future maintenance efforts and accelerated update cycles.

Backend Continuity with Modern Integration

Preserved smooth integration with the existing SOAP-based web service API through HTTP POST and XML payloads. This facilitated uninterrupted server operations during modernization efforts.

Modular Workflow Design

Implemented a user-friendly architecture aligned with the flow of Setup → Search → Configure → Save Project to allow scalable and logical task progression.

End-to-End Project Management

Supported the full project lifecycle with guest/login access, advanced pump search, intelligent configuration tools, and features to create, clone, edit, or delete projects.

Challenges

The legacy server connection method caused crashes on iPhones in distributed builds due to the use of dynamic code, which is disallowed by iOS in final releases.

Xamarin Native had become obsolete and was no longer receiving updates. This left the app vulnerable due to no security updates, lack of platform support, and limited scalability.

Outdated UI led to poor responsiveness and diminished user experience. No support for real-time or async operations, slowing critical workflows.

Complex backend rules demanded precise, risk-free migration.

Solutions

Rishabh Software led a structured, low-risk Xamarin Native to MAUI migration to modernize the mobile app, while preserving business-critical backend logic.

Agile, Incremental Migration

Modules were ported progressively using a sprint-based approach, enabling iterative testing and minimizing downtime.

Seamless Legacy Compatibility

All server-side integration with the existing SOAP API was maintained to ensure continuity of logic and workflows.

Scalable Architecture Alignment

Designed a modular, extensible architecture that mirrors backend logic and supports future enhancements with ease.

iOS Stability Fix with Custom Connection Logic

Rewrote the data connection layer to manually handle send/receive operations, bypassing the iOS restriction on dynamic code. This ensured smooth performance and full compliance on iPhones without altering the app’s behavior or UI.
