UiPath Studio missing namespace

[loginerror (Maciej Kuźmicz)]

Hi @sjankus

What is your Studio version and your packages versions? It seems to be working on 2019.4

You could still try this workaround for older versions:

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.
