One of the most important new features that came with the new Windows 8 OS is the introduction of a new API called Windows Runtime (WinRT). This new API allows us to create Windows apps, a new type of applications built specifically for the new Windows Modern UI. If you are a SharePoint developer you are probably wondering how you can use this new Windows app model to extend your SharePoint solutions? That is what we will investigate in this session. First we will go through the fundamentals of building a Windows app. Then we will see how we can consume the data from SharePoint and leverage its features from those apps to build a new generation of bussiness applications.
