ADO.NET Interview Question: - What are the major differences between classic ADO and ADO.NET?

Following are some major differences between both :- 

  • In ADO we have recordset and in ADO.NET we have dataset.
  • In recordset we can only have one table. If we want to accommodate more than one tables we need to do inner join and fill the recordset. Dataset can have multiple tables.
  • All data persist in XML as compared to classic ADO where data persisted in Binary format also.

This question is taken from .NET interview questions book.
