This is a slide deck I created and used to explain what OAuth is and how to use it with the .NET framework to write clients for Facebook and Google.
My slides usually do not have a lot of text on them so it might be difficult to get the ideas I am trying to convey in each individual slide. They're only relevant with the commentary I present during a talk. I use slides as a secondary tool, the primary one being my narration.
Within May 2015, I will edit and upload the video of my talk on YouTube, and provide a link to the YouTube video here. That may make these slides more useful.
