Cannot use any System.Collections.Generic type on the list - Not All Generic Types Could Be Resolved

[John_Chapman]

I am using Studio 2024.10.6 and am working on the String Bookstores Demo lesson in the Automation Developer Associate training. When I try to define a variable as System.Collections.Generic.List, to make a List I get a popup that declares “Not All Generic Types Could Be Resolved.”

After getting that message, I loaded the solution from the training site, and I see that the variable is defined correctly. But when I try to redefine it, I get the same message.

One screenshot is of the project from the solution loaded where you can see the type correctly defined. The other screen is from when I tied to define a variable as a list of string.

I am rethinking my choice of learning UiPath with the Community version, which is my only choice for earning certificates.

Hey @John_Chapman
You need to choose string type here, then should be fine

Thank you. I was expecting to be prompted for a type as I had experienced with other collections.

@John_Chapman I’m really glad I could help! If you feel my response solved your question, it would be great if you could mark it as the solution — it might help others who face similar issues.

Good luck with your continued learning, and happy automating!
