@Gaurav_Gore you can check the below post

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.

Right click on the xaml file in projects folder and open with notepad ++ and follow the steps in the thread.

If this doesn’t work try downgrading UiPath.System.Acticities dependency

Hi @Gaurav_Gore

Try to import the below namespaces from the imports panels

1.System.Linq
2.System.Linq.Expressions
3.System.Linq.Expressions.Interpreter
4.System.Data.DataSetExtensions

If you still persists the issue,Try by downgrading or upgrading the Packages.

Hope it helps!!
