sounds like it may be the client machine caching the xap file.

If that is your problem, if you clear the cache on the client machine and it
then downloads the new xap file then the fix for this (one I've used anyway)
is to append the modified date/time to the end of the url.
So basically when ever the xap file is updated then the browser will think
its been given a new url and so downloads it (and caches that new one.).
Same app, but different/unique url.

I'm assuming its a Silverlight app, given you've posted it here. :)

if you can't find example code of appending the modified date let me know,
I've got it kicking around somewhere at home. I'm sure its out there tho.

cheers,
Stephen
