Today I just learned from Rick strahl Blog we can get IIS Version using Server variable like

        if (HttpContext.Current != null && HttpContext.Current.Request != null)
        {
            string osversion = HttpContext.Current.Request.ServerVariables["SERVER_SOFTWARE"];
            if (!string.IsNullOrEmpty(osversion))
            {
                //Microsoft-IIS/7.5
                int dashlenth = osversion.LastIndexOf("/");
                if (dashlenth > 0)
                {
                    decimal iisVersion = 0M;
                    if (Decimal.TryParse(osversion.Substring(dashlenth + 1), out iisVersion))
                        return iisVersion;
                }
            }
        }

Thank You
