c# - Why can't I use the modal dialog (child window / top level window) in XBAP application? -

-

i have xbap application , wanted understand why can't use modal windows (child/ top level window) in spite of full trust mode

in other words, why showdialog method asynchronously called when used in xbap?

thanks answer.

the showdialog method in xbap asynchronous - means returns , shows modal window (it works in silverlight). in wpf desktop application method synchronous - behavior comes standard window control.
window shown when call showdialog method still modal, no matter shown asynchronously. there work around that, didn't liked tho : how implement modal dialog xbap
