At the Windows Phone Developer Summit in San Francisco Wednesday, Microsoft provided details on the upcoming Windows Phone 8 operating system.

It promises to provide deep integration with the Windows 8 operating system, meaning that the next generation of Windows devices, from PCs to laptops to tablets to mobile phones, should interact very nicely.

And the new “shared core” between Windows Phone 8 and Windows 8 should provide a lot of benefits when it comes to cross-platform development.

Microsoft announced new additions and tweaks to its next-generation mobile OS, including a revamped user interface, built-in Nokia Maps, support for multicore phones and MicroSD cards, and improved support for various display resolutions.
