--- Comment #18 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming. I've found another app, requiring this API: Cairo Shell v0.3.x
(.NET 4.7 app). Refining summary to reflect this.

Project site: https://cairoshell.com/

https://github.com/cairoshell/cairoshell/releases/tag/v0.3.6842

Prerequisite:

* bug 48611
