If you ever built, or considered building an application for Office you are probably familiar with Visual Studio Tools for Office (VSTO). Now, beginning with the 2013 iteration we have moved to the "Add-in model" for Office applications and that is a good thing. Now we can use our front-end web development skills to deliver Office Add-ins. In this session we will build solutions that will give our Office users tools that can take advantage of the new APIs along with other endpoints integrated into the environment they use every day. Learn how to build Office Add-ins using the same skills we use for SharePoint, web development, Windows and mobile apps, and use the power of the Office 365 platform and the web to deliver contextually relevant information. Deliver solutions that can be used on Windows, iOS and soon Android and MacOS devices. Deliver a huge amount of business value with surprisingly little effort.
