I create a windowsphone silverlight app package -> Blah.Xap
Then I place it in my phone.
In theory,
in 'MainMenu'->'Store'->'...'
there should be an option like:
'Install local apps'
But it didn't show up.
That option shows up when I place *.appx (WRT) file in the phone.
So is there anything setting I should set when build the *.xap from VS studio?
Thanks very much for the answer.
