Copy to Datatable is not a member of System.Array

[loginerror (Maciej Kuźmicz)]

Hi @sangasangasanga

See here:

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.

But also here:

Editing project files is not officially supported

Hi, We would like to remind everyone that manually editing project files such as project.json or the .xaml files is NOT an officially supported way of solving issues. It can lead to unexpected behaviours of Studio when interacting with your project. We cannot provide any guarantees that your project will continue to work after ill-advised changes. Please be careful. Thanks!
