Handoff Design materials to developers in WPF

I am UX expert working mainly on designing web applications. Now the company is thinking moving to develop a window application.

• I am looking for materials around design standards for windows application (while the essence remains the same, there are differences I am sure), and
• What tools should I use for handoff? I currently use Zeplin (which has a xaml extension). Is Microsoft Blend any good? should we stick to the same design process and translate designs to code directly on XAML?

Thanks,

Iris--
