I’ve a simple FlexPendant project in VB.NET with VisualStudio 2005 and RAB 5.10.
When I try to insert an ABB RAB control i.e. a Button in a System.Windows.Forms.UserControl or System.Windows.Forms.Control VisualStudio returns me this error.
I’ve reinstalled the RAB and check all references but the problem is still there.
In the same list, go through each reference and look in its properties.
Check that
[Specific Version], is FALSE
and that the path points to an assembly of the correct version. (I’ve had a case where the reference path was to an old file which was then loaded)
You could also, to make sure, Remove all references and then Add them again to the project.
