Using the new tools included in the Windows Phone 8.1 SDK, it is easier than ever to create apps that share most of their code. Code can be shared using the new shared app template in Visual Studio, as well as by creating Portable Class Libraries. This session walks through the development of a shared app, showing you where code can be shared and where it still makes sense to implement platform-specific features.
Design guru Tommy Lewis wants your apps to look their best. He emphasizes that attractive apps stand out from the rest, so a focus on design is a must. He describes a "visual" way of thinking, covering what to expect during the design phases of your development and what goals to work towards. Last but not least, he covers design principles that you should think about as you design your apps: authentically digital, more with less, pride in craftsmanship, fast and fluid, and win as one.
