Closed Unassigned: 'NET' is not a member of 'GMap.NET.WindowsForms.GMapControl [16121]

Hi.
I have a problem
When i try to build my application i receive the following error:


__Error 40 'NET' is not a member of 'GMap.NET.WindowsForms.GMapControl'.__
at
GMap.NET.WindowsForms.HelperLineOptions.DontShow
and
GMap.NET.MouseWheelZoomType.MousePositionWithoutCenter
and
GMap.NET.WindowsForms.ScaleModes.[Integer]
in designer

When i put Global like this Global.GMap.NET.WindowsForms.HelperLineOptions.DontShow
everything is ok until next time when i try to build the application.
Please help.
