Well, it just might be. Windows Central reported that a UWP version of the WhatsApp App might be under the works. It says that Microsoft and WhatsApp both are working together closely for developing a modern version of the messaging app.
WhatsApp for Windows Phone is based on Silverlight which was something used way back in 2014. But it is one of those few apps which receives regular updates from the developer and has all the features on par with its iOS and Android counterparts.
But if Microsoft’s rumored Andromeda Device comes into action, WhatsApp might not be available for it. Because modern devices based on Andromeda won’t support Silverlight. Luckily, it appears that Microsoft may be working closely with WhatsApp in bringing its Silverlight app to UWP, along with updating its UI with a refreshed interface that features Fluent Design.
This concept art of the work was recently popped up on Behance by a Microsoft-hired designer. Unfortunately, Balance pulled out the listing after Windows Central tried to approach them for a comment. This gave us a clue about the apparent partnership between Microsoft and WhatsApp. The only context surrounding this work is a paragraph on what the project is about:
WhatsApp is a free cross-platform app owned by Facebook. You can make video calls and send text messages, voice messages, documents, and user locations. I have been supporting the team with porting WhatsApp from Silverlight to UWP. We want them to bring their app to Windows 10 desktop and integrate unique Windows 10 features like Ink and Fluent Design. The project had [a] successful result which led to WhatsApp partnering with Microsoft, and we earned high praise from the WhatsApp team
This doesn’t prove that Microsoft and WhatsApp will be launching and app but it does tell us that at least they might be thinking about it. It would be super awesome if Microsoft and WhatsApp actually manage to launch an app like this. WhatsApp UWP app would combine the functionality of both the Windows Phone app and the Windows 10 desktop app available today. On desktops, the UWP app would simply act as a “relay” application allowing users who use WhatsApp on their iOS or Android device and send and receive WhatsApp content directly on their PC via WhatsApp Web syncing.
