Following my previous blog entry about WebSharper.OAuth, I wrote a simple template application that you can use as a base to create your own OAuth-based app. Check out the source, or see it in action.
It features a landing page, a login page, and a private section. It also shows how to query the login provider's API for user information. Also check the Readme, which contains a configuration guide, a walkthrough of the code and a mini-tutorial on how to extend it with a new page.
