Markus,

>>And if you're developing a Windows GUI app today using Microsoft's "official" latest-and-greatest Windows programming environment, WinForms, you're going to have to start over again in two years to support Longhorn and Avalon. Which explains why WinForms is completely stillborn. Hope you haven't invested too much in it.

In the context of the original post (see above), the more interesting question relates to porting WinForms-based apps to completely Avalon-based apps. IOW, if you want your existing WinForms app to no longer use WinForms, but use Avalon forms only, how do you accomplish that?

Will they have some type of transporter wizard, etc? Are the properties and methods of each model vastly different from each other, or is it as simple as "hacking the VCX or SCX" to point to a different form class and perhaps changing a property or two?
