Look inside

Take your C# skills to the next level by implementing smart change detection on a data retrieval app. As a developer at Ground Truth Consulting, you'll enable an application to automatically check for updates across legislative APIs. Store responses to disk and compare new results to spot differences, send alerts to stakeholders when fresh bills are introduced, and build reusable comparison logic to support future data sources. You’ll then add unit tests to validate critical flows, prevent regressions, and refactor with dependency injection for modular and testable code. Whether you're new to C# or a .NET veteran, this project is ideal for leveling up your skills.

This project is designed for learning purposes and is not a complete, production-ready application or solution.

book resources

When you start your liveProject, you get full access to the following books for 90 days.
