There’s never been a better time to move to C#! First-class Azure cloud support, AI Framework integration, and improved code performance in the latest .NET versions all make this an exciting time to be a C# developer. In this series of liveProjects, you’ll turn your existing programming skills into C# mastery by building an app for the agricultural consultancy Ground Truth Consulting (GTC). You’ll go deep into the structural essence of the language, mastering namespaces and classes for organized and reusable code. Learn to make effortless API requests by setting up access to data from the APIs of Congress and the Federal Register, optimize your data storage and retrieval with the efficiency of C# dictionaries, and ensure the reliability and integrity of your software with unit tests crafted using the xUnit framework. With hands-on experience and newfound confidence, you'll navigate the world of C# effortlessly.

These projects are designed for learning purposes and are not complete, production-ready applications or solutions.

I think the liveProject uses various projects to introduce C# pretty well. I especially liked how it encourages me to look at documentations and books, and apply right away to build projects. This really helps me learn fast and easy.

here's what's included

Project 1 Build a Data Retrieval PoC

Hit the ground running with C# by rapidly prototyping a data retrieval app. As a new developer at Ground Truth Consulting, you'll build a proof of concept to streamline legislative monitoring. Tap into .NET's capabilities and set up a data access layer leveraging api.data.gov. Focus on productivity and type safety with C#'s top-level statements, and get hands-on experience querying web APIs and iterating quickly.

Project 2 Create In-memory Data Representations

Level up your C# skills by evolving an API data retrieval prototype into a robust application. As a developer at Ground Truth Consulting, you'll expand the initial Federal Register API demo into a versatile tool to streamline legislative monitoring. This project lets you flex your C# muscles on real-world APIs while prepping for enterprise development. You’ll refactor with classes, tuples, and records for more maintainable code, cache API responses in memory to optimize performance, and integrate the Congress API to showcase multi-source data aggregation.

Project 3 Compare and Evaluate Objects

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.

Project 4 Streamline the PoC

Upgrade a legislative monitoring app with advanced C# features like LINQ and lambdas. As a developer at Ground Truth Consulting, you'll implement detailed change comparisons between API results. You’ll go beyond basic difference detection to provide insight into exactly what changed. Analyze bills line by line to spotlight new amendments, build flexible queries with LINQ to extract and compare key fields, and implement comparison logic concisely with lambdas and delegates. Plus, master professional techniques like parsing complex JSON responses and make an impact by shipping an automated legislative tracking tool ready for production use.

book resources
