Visual Studio c# namespace error

I am shifting an app from WindowsForm to WPF
No change except the UI.
 The WPF app and the WF app refers to a few .dll  (identical in both cases) coming from the sameVS projects.
Trying to add the same references in the new WPF project than in the "old" WF I've got a compile error coming from a "namespace missing...
Enclosed Coparison of the two projects description is a snapshot  showing  differences that i am unable to understand

VSR.CoachLab.Capture.Commands is part of the VSR.CoachLab.Capture project . It appears in WF and not in the WPF project.

Thanks for the help

Check the .NEt version of both projects

Hello Najam
WF is under Net 4.0 and WPF under 4.5.
Downgrading WPF to 4.0 does not change anything, the "name space error" remains the same.
PaulagierResearch DirectorAuthor Commented:
The error comes from a call to a class named ManagementCmds who is an internal static class in the WF project.
Is it possible that, being internal, it can't be used out of the original name space ??
Najam UddinCommented:
no internal is for assembly only, hence can not be used out side
