Microsoft has published the manual with the help of which mobile development specialists who create iPad software applications will be able to switch quickly to developing products for the new Windows 8 platform. The comprehensible manual published at the Windows Dev Center not only explain the most important differences between the iOS environment and Metro interface of the new version of Windows but also describes the behavior of different elements.
The biggest part of this manual is the so-called “contracts”, i.e. mutual obligations between applications and the platform Windows 8 itself. In particular, these “contracts” give applications a possibility to exchange files with each other and with the operating system performing the information search in other applications, outputting the sound to the external devices as well as introducing your own changes into the settings of other applications and systems.
It should be said that the new manual is not direct guidelines on developing applications. It only demonstrates that Microsoft considers the developers of iPad software applications as the most important part of its strategy on creating the new ecosystem of applications that is planned for launching for tablets with the operating system Windows 8. At present Microsoft repeats its approach to the Windows Phone platform where the producer very often entices mobile developers from the iPhone platform. The efforts of Microsoft not once have led to a privileged delivery of additional tools for porting apps on the new platform, and sometimes mobile apps developers directly pay for the development of the new versions for Windows Phone with guarantees in case of unstable sales of these versions.
At present the Windows Phone API Mapping Tool already supports the iOS and Android platforms and performs the function of a translator between Windows Phone and other mobile operating systems. Using it, 
based devices.
Oliver Block, one of Windows CE developers, wrote in his diary that participants of the last conference devoted to integrated systems in San Jose asked him the same questions. They were interested if CE was killed by its developers going forward to the ARM-platform, or if developers were using Visual Studio and whether all Windows Embedded products were based on different SKU.
