I have heard "modern clients only". What is this about?

Businesses and users want to be reassured that only the newest, most advanced, and up-to-date tools are being used to access their data. With Business Central 2019 release wave 2, released October 2019, users switch to the modern experience in the browser ("the web client"), the Android or iOS mobile apps, or the Windows 10 desktop app, which are available through the respective stores.

Connecting the Windows client to Business Central is not supported in Business Central 2019 release wave 2 and onwards.

Why is Microsoft discontinuing the Windows client?

Our customers must feel comfortable that the tools they use are fit for new hardware, operating systems, and changing environments. We have accelerated our investment in speed and productivity features for the modern clients, thereby achieving a major milestone in its transformation into a world-class desktop experience for both new and expert users.

While the Windows client was inherently bound to the Windows operating system, the modern clients allow us to reach more customers and more users within an organization, no matter their platform or device of choice. The latest technologies allow us to innovate at a rapid pace and respond to accelerating compliance requirements, the changing technology landscape, and requests from the community. In addition, the lower installation footprint on client devices makes it easier for IT departments and hosters to maintain and support their user base.

When is the Windows client discontinued in Business Central?
