Edit .csproj :

It sounds like you want to develop a feature for an app that runs on using .NET 8.0 (the runtime version) and is intended for Windows 11 (or Windows 10/11 with modern APIs). It includes the Common Language Runtime (CLR), which

private bool IsWindows11OrNewer() => Environment.OSVersion.Version.Major >= 10 && Environment.OSVersion.Version.Build >= 22000; } private bool IsWindows11OrNewer() => Environment

is an essential, behind-the-scenes component for the Windows ecosystem. It is a non-feature update, meaning it does not change how your apps look or add new buttons, but it is critical for patching security holes and ensuring the stability of the software you use daily. It is highly recommended to install this update if prompted by Windows Update or a specific application.
