Hi @MitheshBolla ,

Have you tried following the Steps in the Below Post :

Compile Error: "AsEnumerable" is not a member of "System.Data.DataTable"

@VegitlX_HuNteR Follow these Steps and Check : Open your Main.xaml File in Notepad or Notepad++ or any other Editing Tool. Then Add the Highlighted Reference as an Assembly Reference in the Assembly Reference Section as Shown in the Below Image. [Capture] Make sure to Close your xaml and then after the Edit open it again.

Also, Do Check if System.Linq is imported in your xaml first by checking in the imports section.
