Hi @Chiru

Could you reproduce this on a separate, new project and share the zip file?

This way I could open your project as is (with all yours dependencies) and try to reproduce

you can pass array in datarow activity then add that datarow in datatable

Thanks

Hi @Chiru

What version of Studio is it?

There is also this workaround available:

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.

Hey @loginerror

Thanks for the solution/ fix.

BTW I’m using the studio v20.10.6 and still see this issue. So, I would like to understand the reason for that error and if there is any an officially supported way of solving issues !!

Thanks in advance.

This should have been fixed in that version, actually. It is fixed only for new projects though.
