Look inside

Welcome to Boutique, a software development company that’s working on a project to automate a client’s inspection process. As a software engineer, your task is to create an HTTP API for the project. You’ll set up an ASP.NET Core web host, implementing the first endpoint according to the OpenAPI specification. To verify the endpoint works as intended, you’ll add integration tests, and you’ll use Swashbuckle and API versioning middleware to enable future functionality. When you’re done, you’ll have firsthand experience with important tools—including Postman and Swagger UI—and an API that’s ready for further development.

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

Ruben Vandeginste

Ruben Vandeginste received his PhD in computer science from KU Leuven, Belgium, in 2007. Soon afterward, he began working for PeopleWare, where he’s currently a software architect and technical lead. He designs and helps implement administrative applications, with a focus on backend services built with Microsoft’s .NET stack, and he’s well-versed in implementing HTTP APIs with Web API and ASP.NET Core.


This liveProject is for C# developers who want to learn how to create an HTTP API using the ASP.NET Core framework. To begin this liveProject, you’ll need to be familiar with the following:

  • Basic C#
  • Basic HTTP
  • Basic YAML and JSON
  • Basic debugging techniques

you will learn

In this liveProject, you’ll learn to create an HTTP API using ASP.NET Core, enable future functionality using middleware, and manually test endpoints.

  • Set up an HTTP API host with ASP.NET Core
  • Configure and use the Microsoft dependency injection (DI) container
  • Basics of reading an OpenAPI specification
  • Implement endpoints using attribute-based routing
  • Write integration tests for endpoints
  • Use Postman for manual testing of the API
  • Set up Swagger UI using middleware
  • Set up API versioning using middleware
