UWP and WinUI - How to check my OS version through C#

Question

Hello. I'd like to check the user Operational System through C# in UWP and WinUI. In my case, I'd like a method to return if the OS is Windows 10 or 11. I've tried:
var os = Environment.OSVersion; OperatingSystem opSys = new OperatingSystem(os.Platform, os.Version);

But the Version is Win32NT for Windows 10 and 11 in both cases.

Hello @Anderson Rodrigues Cavalcante ,

Welcome to Microsoft Q&A!

It is recommended to use Windows.System.Profile.AnalyticsInfo.VersionInfo.DeviceFamilyVersion, you can get OS build information from it.

• Windows 11 release information
• Windows 10 release information

The OS build of Win11 starts from 22000. If the build is smaller than 22000, it can determine that the current OS is Win10.

string deviceFamilyVersion = Windows.System.Profile.AnalyticsInfo.VersionInfo.DeviceFamilyVersion;
ulong version = ulong.Parse(deviceFamilyVersion);
ulong major = (version & 0xFFFF000000000000L) >> 48;
ulong minor = (version & 0x0000FFFF00000000L) >> 32;
ulong build = (version & 0x00000000FFFF0000L) >> 16;
ulong revision = (version & 0x000000000000FFFFL);
var osVersion = $"{major}.{minor}.{build}.{revision}";
            
if (build >= 22000)
{
    Debug.WriteLine("win11");
}
else
{
    Debug.WriteLine("win10");
}

Thank you.
