How to use all members from imported namespace

[jan]

Hello everyone, please can someone tell me if it is possible to use all the members from imported namespace. If i create a custom activity which references this assembly i am still able to access only the members that were used in activity’s code(e.g. constants under UiPath.Activities ). For example if i try to use Microsoft.Office.Interop.Excel.Workbook object these are all the members that are available in UiPath studio vs all members of this class.

Thank you

In case anyone would be interested
To include all the members (not just the ones used in the code) you need to change this option for the reference for your project to False.
