Whats the workaround, long term fix

[KP6689 (KP)]

These two issues:

AsEnumerable is not a member of 'System.Data.Datatable'

Hi @lucas.mcgonagle EDIT 20.10 fixed this issue for newly created projects. You can fix it by adding the Assembly Reference manually in your xaml file: [image] Simply open the file in Notepad and create new line with this String: <AssemblyReference>System.Data.DataSetExtensions</AssemblyReference> Then reopen your project and the error should be gone. Please be careful while doing so and always keep a backup.

Editing project files is not officially supported

Good advice, I will stay with the reinstallation. MaryB

whats the solution probably

1. reinstalling
2. paid-version
3. other?

Hi @KP6689

I believe it should already work well if you simply update the UiPath.System and UiPath.UiAutomation activity packages to the latest versions
