What are the similarities between XBAP and SilverlightTM ?
Both XBAP and SilverlightTM are used for creating Rich Internet Applications.
They are both based on the XAML format and run inside the browser.
What are the differences between XBAP and SilverlightTM ?
XBAP is Windows only and requires .Net 3 Framework to be installed on
your machine. It is used for creating heavyweight .Net applications that take
advantage of the full capabilities of .Net 3 Framework.
SilverlightTM is a small component that is plugged into the browser.
It is cross platform and does not require the installation of .Net 3 Framework.
SilverlightTM supports only a subset of XAML. You may think of SilverlightTM (WPF/E) as
Microsoft's equivalent to Flash Player.
