Download WPF/E Community Technology Preview

WPF/E by Microsoft delivers rich, cross-platform, interactive experiences including animation, graphics, audio, and video for the Web.

Download and install the Community Technology Preview (CTP) release of the WPF/E Software Development Kit (SDK) that enables you to build rich browser-based experiences with animation, video and audio simply using web-standards friendly AJAX and XAML for presentation. The SDK contains documentation, code samples, and tools for designers and developers. It is expected to be freely available for customers in the first half of 2007.

Abhishek Kant says that WPF/E is an alternative to flash.

“The technology is currently in BETA and is a subset of its desktop counterpart - WPF. This technology can not only run on Windows but also on Mac and in future on Linux as well. When you run any WPF/E application, it would first install a runtime of around 2 MB. This is different from .NET 2.0 or 3.0. the tool currently being envisaged for use with WPF/E is Expression Interactive Designer that works using XAML. As of today, one can design UIs using the Interactive Designer and then import it into WPF/E (that also uses XAML).”

If all that sounds like jargon, some tips below
