Quote:

Microsoft recognized that something brand new was needed that escaped the limitations
of GDI+ and USER yet provided the kind of productivity that people enjoy with frameworks
like Windows Forms. And with the continual rise of cross-platform applications
based on HTML and JavaScript, Windows desperately needed a technology that’s as fun
and easy to use as these, yet with the power to exploit the capabilities of the local
computer. Windows Presentation Foundation (WPF) is the answer for software developers
and graphic designers who want to create modern user experiences without having to
master several difficult technologies. Although “Presentation” sounds like a lofty term for
what I would simply call a user interface, it’s probably more appropriate for describing the
higher level of visual polish that’s expected of today’s applications and the wide range of
functionality included in WPF!

Quote:

In short, WPF aims to combine the best
attributes of systems such as DirectX
(3D and hardware acceleration),
Windows Forms (developer productivity),
Adobe Flash (powerful animation
support), and HTML (declarative
markup).

If it were to separate UI completely with the behaviour, aren't the developers doing that already with clean layering architecture with the forms based applications?

and why somebody would like to load a desktop application on a browser? If its a browser based application, it should be developed in ASP.NET
