Hi Lucas,

I got the solution for this issue.

Even after importing the IO.Compression namespace you cant get the System.IO.Compression.filesystem assembly.

What we need to do is convert the .dll file into a nuget package and place the package under “C:\Program Files (x86)\UiPath Platform\Packages”

Then we need open the .xmal file in a notepad and place mention the assembly manually like below


By doing this we can use the assembly in uipath studio
