Progressive .NET Tutorial

August 2nd, 2011  |  Published in Events, REST by Ian Robinson  |  3 Comments

On September 7th I’ll be running a half-day tutorial on building RESTful Web services as part of the Skills Matter and London .NET User Group’s Progressive .NET Tutorials.

This will be a very hands-on tutorial. Over the course of three and a half hours we’ll build a hypermedia-driven service and client in .NET using the new WCF Web APIs. The subject matter hearkens back to a favourite subject of mine, Hydras and Hypermedia, for the application we’ll build will be a simple text-based pick-your-path-to-adventure game.

This isn’t a tutorial on games design, however. Despite the non-enterprisey subject matter, the tutorial serves to illustrate how machine clients and services can cooperate to achieve a useful application goal. Business application analogies lurk around every corner and surprise you with every encounter.

The tutorial comprises three exercises. With each exercise you’ll have to fix a number of broken unit and functional tests. Bit by bit, you’ll build a working application:

  • Exercise 1: Here we implement the server resources that make up the dungeon – the chambers, tunnels and caves in which our daring client will venture.
  • Exercise 2: Next we build a crafty client that can discover a path through the dungeon. By the end of the exercise, the client ought to be able to navigate the dungeon from entrance to exit.
  • Exercise 3: Last, we add an element of danger, populating the dungeon with encounters (more resources) that the client must overcome before it achieves its application goal.

Along the way you’ll learn about:

  • The Atom Syndication Format
  • “What if” client-side intelligence
  • The client as arbiter of application state
  • Hypermedia controls: links, link relations and forms
  • DRY URIs

So come and join me for what promises to be an entertaining hack-n-slash workshop. Attendees should be familiar with C# and unit testing, and have some knowledge of HTTP.

    Any chance you will be publishing the material/presentation after it’s over to those that could not attend?

    Hi Ron

    I’ll almost certainly make the material available in some form after the tutorial. In addition, Skills Matter may record the sessions, to help fill in the blanks in the code and docs.

    Kind regards

    Ian, I am looking forward to the session very much. I am traveling to London from Atlanta to attend the SkillsMatter sessions.

    See you there!
    take care,
