What is XBAP?
Sunday, January 14th, 2007XBAP (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)
