The company will release developer tools for Mango in May. Key new features in the kit include multitasking, deeper phone integration and access to the camera and motion sensors, so that developers can build apps that better use the phone’s hardware.

The multitasking option on the phone adds a few functionalities such as the ability to listen to streaming music while using other applications. ReadWriteWeb reported from the conference that Microsoft will add file transfers and the ability to quickly swap between apps as well.

Deeper phone integration means that developers will be able to change more about the phone’s display, such as the color of the live tiles. It also means that developers should be able to access user contacts and calendars to integrate with app features.
