For anybody that is attending, the app is essential and provides the ability to find information on sessions, speakers, as well as leaving that all important feedback to let them know how they did. The app also has handy venue maps to help you navigate around.
The actually conference kicks off on April 29th and has 3 days of sessions packed with the latest and greatest developer information on Office 365, Azure, Windows 10, and much more. If you weren't lucky enough to get tickets to the main show, don't forget about the Build Tour which will be making its way to 29 cities around the world.
Our own @bdsams will also be attending BUILD too, so keep it locked here and we will keep you updated on all that is happening as well.
