Is this news legit? Well, that depends on how legit is the ‘Microsoft Developer Network page’. Because this page has just listed out all the APIs in Silverlight for Windows Phone 7.1, and what’s this 7.1?

Microsoft never mentioned this version 7.1 thing, and the only update that we know coming from Microsoft for their new Windows Phone is ‘Mango’. Previously we’ve heard that ‘Mango’ will be version 7.5, but that was based on supposition more than anything else, and a .1 upgrade makes sense in light of the current 7.0.7 version number. It just doesn’t make sense to jump away so much right?
