The video of my talk at //build 2014 is online: http://channel9.msdn.com/Events/Build/2014/2-638. "Understanding Customer Patterns: Instrumenting Your App for Telemetry and Analytics." The written version of this is what I published on the App Builder's blog recently: http://blogs.windows.com/windows/b/appbuilder/archive/2014/03/20/instrumenting-your-app-for-telemetry-and-analytics.aspx.
Thanks to everyone that downloaded my 15+Puzzle app and played with it a bit. I also had a number of folks in the audience do it during the talk, which made a compelling presentation. And yes, I did give away all the prizes I had…about 6 people approached me afterwards showing the app with a medal. 🙂
