Hi @Sim_rpa 1. Check the references in your project: - Open your project in UiPath Studio. - Go to the Project panel on the left-hand side. - Expand the Dependencies section and check if there are any references to System.Data.Common or System.Data.DataTable. 1. Remove and re-add the references: - Right-click on the references related to System.Data.Common and System.Data.DataTable. - Select Remove to remove the references. - Right-click on the Dependencies section and select Manage Packages. - In the Package Manager, search for System.Data.Common and System.Data.DataTable. - Install the appropriate packages that match your project’s requirements. 1. Clean and rebuild your project: - Go to the Build menu and select Clean Solution. - Once the solution is cleaned, go to the Build menu again and select Rebuild Solution. 1. Restart UiPath Studio: - Close UiPath Studio completely and reopen it. I hope it helps!! ---

And I found the following. I uninstalled the original and installed Version19.12.0 preview, and this made the error for “AsEnumerable” not part of “System.Data.DataTable” disappear, which was my issue.

in projects tab you can expand each package to see what what references they have. Go and expand each one to see which package contains **system.data.common** then uinstall/reinstall that package ![image](https://global.discourse-cdn.com/uipath/original/4X/f/6/7/f67629a1bd0632da5abeac148b14d618bbe61b6c.png) ---
