This document provides an overview of tools and concepts for developing Windows 8 applications using the ImmobilienScout24 REST API. It discusses downloading and installing Windows 8, Visual Studio Express for Windows 8 development, and the basic concepts of using C# objects with mock data, binding to XAML pages, and retrieving "real data" from the ImmobilienScout24 API. It also outlines some known issues like the lack of a map control and limitations of list controls, and provides workarounds.
