I've just run into a MAUI issue which is specific to Windows (works fine on Android), and so I looked for a Windows Lemmy Community and was surprised to find there wasn't one! So I have created one at !windows_dev@programming.dev
Of course you are still welcome to post about MAUI issues in !dotnetmaui@programming.dev but if the issue is specific to Windows (as I have just encountered) then there is now the Windows Development Community as well (and of course we already have Communities for Android and IOS development, for issues on those platforms).
