There isn't any such method, but you can use this method that checks it conditionally:

    public static OSPlatform GetOperatingSystem()
    {
        if (RuntimeInformation.IsOSPlatform(OSPlatform.OSX))
        {
            return OSPlatform.OSX;
        }

        if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
        {
            return OSPlatform.Linux;
        }

        if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
        {
            return OSPlatform.Windows;
        }

        throw new Exception("Cannot determine operating system!");
    }
