Microsoft announces Teams Progressive Web App (PWA) preview for Windows 10 S

It's only the first day of Build 2018, but we've already seen a flurry of announcements about AI, the intelligent edge, and new developer tools. Somewhat buried in the whirlwind of announcements, however, is that Microsoft has launched a preview of the Teams app (opens in new tab) for the Microsoft Store -- and it's a Progressive Web App (PWA) (opens in new tab).

Microsoft originally promised Teams would be one of the first PWAs to hit the Microsoft Store during its Edge Web Summit in 2017. PWAs only just began arriving on the Microsoft Store alongside the April 2018 Update, so Microsoft's timing is certainly in line here. The only catch? The app is only available for Windows 10 S / S-Mode devices for now.

From Microsoft:

At Build we are excited to announce the preview of the Teams app for the Microsoft Store. This release marks an important step in our ongoing efforts to support Progressive Web App (PWA) capabilities in Windows, using Edge based rendering and combining web technologies with native OS capabilities to deliver an innovative new experience. As a Store app, it is installed and managed through the Microsoft Store, supports the Narrator screen reader, and integrates with the Windows 10 Action Center. For Public Preview, the Teams Store app is only available for Windows 10 S / S-mode devices.

The Microsoft Store app comes alongside new features Microsoft is debuting for Teams as well. Those include a new mixed reality experience called Microsoft Remote Assist, which interfaces with Teams. The service is also getting adaptive card support soon in preview, which allows developers to send actionable cards from their bots, connectors, and extensions. "Adaptive cards allow you to send more flexible content in conversations and are supported on other Microsoft platforms such as Outlook, Windows, and Cortana," Microsoft says.

  • good job ms
  • Indeed! Hope it works a bit snappier than the desktop version which I found a bit sluggish... Also hope they will add support for different O365 tenants asap!
    That's one advantage that Slack still has imho...
  • On Windows 10 S?
    That's a very very small market! 🙄
  • Probably that's why it launches there.
  • It's likely going to grow though. Especially since companies will get the benefits of Chrome OS and Windows 10 in one solution all while without going through the complicated migration process.
  • So, can someone give me an explanation, and a simple one as I'm not the brightest spark, why all new app from Microsoft is not being developed using the UWP structure? I understand that some applications may rely on tightly-integrated Win32 APIs like virtualisation, etc. but why is Teams PWA? No wonder developers are looking at UWP (WinRT platform) and questioning its value if the company that made it isn't couldn't even be arsed using it. It's like Ford providing Toyotas for its fleet of company cars.
