Jeff Wilcox, developer of successful Windows Phone App 4th & Mayor will deliver a 300-level talk that looks into what it takes to create a large Windows Phone app, from dealing with the marketplace, solving common problems, and a look at a smart data caching and loading system for pulling down data from web services. Even if you are building small apps Jeff will show you how to polish it and make a difference by adding visual effects, addressing usability and design issues, as well as adding error reporting and other key app services.
