How does a tool that allows you to re-work your existing iOS or Android source projects into Win10 projects compare to a tool that allows you to convert a document from 1-2-3 or WP into Excel/Word? Or rather, how could it possibly lock a software developer into the Windows platform? This is more like a life-support tactic to allow developers to publish to mobile Windows with minimal effort, with the hope that the platform catches enough traction that developers would start developing native Windows 10 mobile apps. This is identical to what Blackberry did with BB10 to allow developers to publish Android apps that supported it (which I've done at my work). That certainly did absolutely nothing to lock me into the BB10 platform (though it did not make me want to develop for the platform any more than I did).
Why would they want to do this? MS providing a "reworking"/"publishing" tool that lets you easily port iOS and Android apps to Win10 means that more developers are targeting non-MS platforms as their primary platforms. This sounds more like MS is signalling, "We haven't been very successful with this, so we're going to follow your lead for now." There's been a pretty radical culture change in the DevTools/Frameworks/Runtimes teams at Microsoft, signalled by the fact that all of their core runtimes and web frameworks are 100% open source (APL2), published on GitHub (https://github.com/aspnet) and are directly accepting and responding to issue reports and pull requests on these projects. Their new DNX runtime (in preview right now) targets Windows, Linux and MacOS (through Wine, which they are contributing to) and (almost) all of their example code for the new ASPNET5 frameworks is developable and deployable on all three platforms.
3 years ago I would never imagine myself ever recommending any MS development tools to anybody, but here I am now
Btw, Visual Studio 2015 Pro is now 100% free for small organizations or open source projects (branded as Community edition).
they have no problme in programming
Nope. No problme at all, I'm sure they'll see their typo.
