Prior to working at Microsoft, I had some customers who wanted
to dual target both WPF and Silverlight. Since then, Windows Phone 7 has
been added into the mix. With all these similar technologies, all
using xaml, multi-targeting applications can be a reality. It's not
without its challenges, however.
At DevLink 2010, I presented my "Dual Targeting" talk. I've
presented this talk at a few conferences. With the addition of WP7,
maybe I need to change it to "multi-targeting" as xaml hits more
platforms :)
I discuss which things are easiest to share, and which are
hardest. I also recommend some approaches on how to structure your
project, as well as a comparison of the different ways by which you
can share code and xaml. I cover assembly portability, code sharing
using linked files, usercontrol encapsulation and abstraction, and
even loading xaml at runtime after futzing with the source via
code.
Zip file with slides and VS2010 source code attached. The source
doesn't have all the examples, but does include the main scenarios.
You'll need VS2010, .NET 4 and Silverlight 4 to open the
solution.
(NOTE: You'll need to add a reference to system.xaml in
the ReuseLibWpf project to fix the compile error. My
bad)
