WPF control in Photoshop

I want to develop a plugin that has minimum interaction with the host application. For example, once the plugin is loaded, the user is able to open and edit images on the plugin interface. The images can then be saved from the plugin dialog without the need to go through host application. Basically, the plugin will not have any interaction with the host except it will appear in the photoshop drop down menu (for that we need to code PiPL resource I guess?).

I need richer controls in my dialog interface, is it possible to use WPF (windows presentation foundation) forms and user controls instead of using MFC dialog provided in the sample code? Is WPF fully supported by photshop sdk?

Thanks for any help:)
