Hi
Julien,
I guest you are using Xaml binaries and this is the cause of the error
In the attached project the
implicit styles approach and NoXaml binaries are used. In that case you don't need to copy the whole styles and all resources because they have been inherited from the merged resource dictionaries. I've updated the project where I've included the GanttView resources.
Please take a look and let me know if this helps.
