AssociationType.ClassOfExtension is not working when selecting different format like .txt .pdf .xml, it is only working with AllFiles or with only .txt

Version of SharpShell used: 2.7.2

Hello, I'm trying to get my context menu for specific file format.

It is only working if I use this [COMServerAssociation(AssociationType.AllFiles)] Or if I use this: [COMServerAssociation(AssociationType.ClassOfExtension, ".txt")]

Whenever I select another single file format or several , it does not work. [COMServerAssociation(AssociationType.ClassOfExtension, ".pdf")] or [COMServerAssociation(AssociationType.ClassOfExtension, ".jpg", ".png", ".bmp")]

I read that we could try with the obsolete FileExtension, but it doesn't help. Should we filter the file format in the CanShowMenu() as a workaround?

Thanks for your help,

Thib
