Microsoft has released a new iPhone/iOS to Windows Phone 7 API Mapping Tool with a view to help developers port over iPhone and iOS apps to the Window Phone 7 platform.
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 code samples allow developers to quickly migrate short blobs of iOS code to the equivalent C# code. All WP7 API documentations are pulled in from the Silverlight, C# and XNA sources on MSDN.
You can also share your suggestions for the API Mapping from iPhone to Windows Phone 7. Share what libraries, classes, methods you’ll like to see a mapping for, here.
