it will fit, it will work, dual slot means that you cannot use the slot near the videocard because of the cooler but it does not mean that it will use two slots interfaces, it uses just one. Dont worry, as long your case has space for it, it will work.
Thank you for your fast reply. I am getting a new case next week and looked up if the GTX 1050Ti will fit in and it will, so I am happy that everything will work as expected. :-)
