* A helpful and responsive support team backs up what is a well-featured and usable library of controls for WP8 RAD development * Syncfusion's library represents a collection of controls and capabilities not found in the native toolbox, including range slider, numeric textbox, busy indicator, and various gauges and pickers and layout-based controls. Using the library represents time-saved when developing dashboards, information tools or phone apps where functional and descriptive UI is a requirement. The inclusion of easy-to-use charts means it's likely this library will become a de facto install for much WP8 development. Visually, the controls map well to 'Metro' theming, whilst offering several options for customisation. It should be noted, the product is in beta (May '13), so there are "bumps" here and there, but an easy to use support interface at the syncfusion website means communicating with the dev team is simple and quick, and in my personal experience, leads to workable resolutions in the event of bugs, etc.
