Building REST APIs with .NET (hands on workshop)

Fusion workshops bring you industry leading experts to help inspire and educate software professionals looking to upskill.

About this Event

Fusion Workshops brings you the first workshop of 2021 with Dylan Beattie. After running a number of hugely successful sessions with us last year, Dylan is back to train Developers on a whole host of new topics! This time we are covering ‘Real World REST with C# and .NET’.


This workshop is perfect for software teams who are creating APIs and want to understand the benefits of REST as an architectural style, for experienced developers who want to apply RESTful patterns and ideas in their projects, and for junior developers looking to broaden their knowledge.


This will be a two day online technical ‘deep-dive’, where you will explore all the patterns and ideas behind REST through a series of hands-on exercises, and learn how to apply those patterns and ideas to real world projects.


Key Takeaways from this workshop

  • Learn how to design and implement RESTful APIs in C# and ASP.NET Core.
  • Learn how to use the full range of HTTP verbs and response codes effectively.
  • Learn about the various hypermedia formats that are available for building HTTP APIs.
  • Learn about the rich set of tools that can help you design, build and manage your APIs.


Most developers have heard of the architectural style known as REST, but even experienced developers often find it difficult to apply RESTful principles when building real-world applications. This workshop is all about building and running RESTful systems in the real world.


Over two days, you’ll get a comprehensive grounding in the principles and patterns behind HTTP APIs, the architectural style known as REST, and the frameworks and formats that exist to support developers building HTTP APIs using C# and Microsoft .NET. We’ll start by going right back to Roy Fielding’s original thesis “Architectural Styles and the Design of Network-based Software Architectures”, in which he describes the set of constraints that define this much-misunderstood architectural style. We’ll learn the significance of each of these constraints, and explore some examples of real-world systems that demonstrate each constraint in action.


We’ll look in depth at how to use Microsoft’s own ASP.NET Core framework to build and host high-performance REST APIs. We’ll discuss how running on .NET Core opens up new possibilities for developing and hosting your APIs, from cross-platform IDEs like Rider and Visual Studio Code, to running .NET Core on Linux and using serverless hosting environments like AWS Lambda. We’ll explore the various formats that exist for representing hypermedia resources in JSON – HAL, SIREN, HYDRA, JSON-LD and Collection+JSON, and the relative merits of each. We’ll go beyond 200 OK and 404 Not Found and explore how you can use the full range of HTTP verbs, headers and response codes to build expressive, responsive APIs. We’ll look at ways of securing your HTTP APIs, and techniques and patterns you can use to document and test your APIs in development, and monitor them when they’re running in production.


Finally, to put all this in context, we’ll talk about why REST might not always be the best solution to your problem, look briefly at some of the alternative API patterns you may want to consider using, and finish up with some discussion of how RESTful services can fit into your organisation’s technology strategy – and how to persuade your boss, and your team, that they’re worth investing in.


You’ll leave the workshop with a comprehensive understanding of building HTTP APIs in C# and .NET, your own working implementations of the patterns and techniques we’ve talked about, and a much clearer idea of what REST is – and why people are still talking about it, nearly twenty years after it was first defined.
