If I use: Common.Globals.HostSettings - I get: Obsolete use: Host.GetHostSettingDictionary

When I use Host.GetHostSettingDictionary it claims it is not a member of Host.
When I check the object browser I find DotNetNuke.Entities.Host.HostSettings.GetHostSetting
If I use DotNetNuke.Entities.Host.HostSettings.GetHostSetting this is now obsolete use: Common.Globals.HostSettings

Please give advice
