XBAP (XAML Browser Application) is a new Windows technology used for
creating Rich Internet Applications.
While windows applications are normally compiled to an .exe
file, browser applications are compiled to an extension .xbap and
can be run inside Internet Explorer.
Xbap applications are run within a security sandbox to prevent
untrusted applications from controlling local system resources.
(e.g deleting local files)
