Does Windows 11's new Snap feature only work with certain applications?

Just installed the Windows 11 Preview, if I hover over the maximise button in Notepad, I see the new snap dialog:

Snap working in Notepad in Windows 11

But in an application like Visual Studio 2022 Preview (1.1), I don't see it:

Snap not working in VS 2022 Preview

Do applications have to be configured to support this, or is this a bug with the Windows 11 Preview build?

More to the point, do I as an Application Developer need to make changes to my application to support this feature in Windows 11?

Thanks


It seems that currently (preview build 22000.51) Windows 11 Snap layouts do not show when hovering over the maximize button for applications using a custom non-Win32/UWP title bar.

You can use the ⊞ Win + Z keyboard shortcut to open the Snap layouts menu instead. I tried this on Windows 11 and it worked for applications like Firefox, Visual Studio 2022 Preview, VS Code, and Discord.
