regionSEE | Field Tracking Platform Migrated Off Silverlight

Client / Industry

Field workforce tracking & scheduling

Existing Technology Stack

Silverlight (deprecated Microsoft browser-plugin framework)

🛑 The Business Challenge

regionSEE's original front end was built on Silverlight - a Microsoft browser-plugin framework that has since been deprecated and dropped from modern browsers. A plugin-dependent UI is a dead end: it can't run on mobile, and its long-term viability was tied to a technology Microsoft had already stopped investing in.

• Plugin dependency: Silverlight requires a browser plugin that modern browsers no longer support
• No mobile support: a plugin-based UI cannot run on phones or tablets
• Deprecated platform risk: continuing to build on Silverlight meant building on a technology with no future
• Feature parity: the rebuild needed to preserve employee tracking, scheduling, and reporting without disrupting active users

Modernization Strategy

Full technology migration off the Silverlight plugin onto server-rendered ASP.NET MVC 5.0

Solution: Plugin-Free Platform Migration

We rebuilt the application's front end on ASP.NET MVC 5.0 as standard responsive HTML, removing the Silverlight plugin dependency entirely while carrying over the platform's core functionality.

• Framework Migration: Replaced the Silverlight client with server-rendered ASP.NET MVC 5.0 views enhanced with AngularJS and jQuery
• Mapping & Tracking: Rebuilt employee and customer location tracking on the Google Maps API
• Scheduling & Reporting: Carried over the scheduler and reporting modules used to manage field visits
• Responsive Design: Rebuilt the admin and field UI to work across desktop, tablet, and mobile - impossible under the old plugin-based front end

Migration & Testing Approach

Rebuilt the front end from scratch on MVC 5.0 while preserving the underlying tracking, scheduling, and reporting functionality
