How to use all members from imported namespace

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 :wink:

In case anyone would be interested :slight_smile:
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.
