How to get OS' version?

[JanVargovsky]

Hi,
how do I get correct Windows runtime version that is listed in "winver" command?

when I execute command "winver" it returns "Version 1709 (OS Build 16299.371)"

.NET Core 2.0 app:
System.Environment.OSVersion returns "Microsoft Windows NT 6.2.9200.0"
System.Runtime.InteropServices.RuntimeInformation.OSDescription returns "Microsoft Windows 10.0.16299 "

Do I have to manually extract it form the OSDescription?

Thanks

Seems like System.Environment.OSVersion is unmaintained (should be Obsolete though).

Alternative is Microsoft.DotNet.PlatformAbstractions.RuntimeEnvironment.OperatingSystemVersion in the Microsoft.DotNet.PlatformAbstractions nuget package.

On Win10, OSVersion for 2.1 returned 10.0.x, however with 3.0, it returns 6.2.x. Although the documentation says it is unreliable, this is a regression and breaking some PSCore6 tests that were relying on this and likely customer scripts as well.

@SteveL-MSFT please file a new bug, let's not hijack long-closed issues.
BTW: This is long-term source of pain. It may have been by-design breaking change in an attempt to fix the space ... let's see what area experts say on the new issue.
