Microsoft is aiming to assuage the pains of mobile application developers looking to migrate their iOS applications from Apple’s mobile operating system to Windows Phone. “Launched today, the iPhone/iOS to Windows Phone 7 API mapping tool helps developers find their way around when they discover the Windows Phone platform,” writes Microsoft in a blog post. “Think of the API mapping tool as being like a translation dictionary.” The tool will allow iOS developers to easily find the equivalent API calls, classes, methods, and notification events in C#, as well as download working bits of sample code. “Don’t expect a mapping for all of the APIs, simply because the platforms are built upon different architectures and user interfaces,” the post continues. “For this first round we focused on identifying the one-to-one mapping when it exists. In the following versions we’ll expand the scope and anytime the concepts are similar enough, we’ll do our best to provide the appropriate guidance.” Microsoft’s tool can be found here.
