Remarks

In .NET versions prior to .NET 5, Environment.OSVersion returns an OS version that may be incorrect when an application runs under Windows compatibility mode. For more information, see GetVersionExA function remarks. In .NET 5 and later versions, Environment.OSVersion always returns the actual OS version. For more information, see Environment.OSVersion returns the correct operating system version.

To identify the operating system platform, for example, Linux or Windows, you can use the RuntimeInformation.IsOSPlatform method.
