Error: "AsEnumerable" not part of "System.Data.DataTable"

@MaryB2019
Once WE do face the Error Message WE Just add the Missing namespace manually. This ist solving without any reinstallations or Others removal. Just Close and reopen the xaml

Manually Addition

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.
