Microsoft released a developer tool that is aimed at helping iPhone developers port their applications more easily to Windows Phones. Microsoft officials described the new API (application programming interface) mapping tool as similar to a translation dictionary.
From the Windows Phone Developer Blog
With this tool, iPhone developers can grab their apps, pick out the iOS API calls, and quickly look up the equivalent classes, methods and notification events in WP7. A developer can search a given iOS API call and find the equivalent WP7 along with C# sample codes and API documentations for both platforms. The first iteration of the tool focuses on network/Internet, user interface and management APIs. Microsoft officials said not to expect a mapping for all of the APIs, as the two phone platforms are built on different architectures and user interface.
Information for Interested Developers
Microsoft is looking for developers to suggest other APIs they’d like to see mapped, and also is providing interested developers with a 90-plus page “Windows Phone 7 Guide for iPhone Application Developers” white paper.
