ASP.NET - LINQ Benefits

Question

I have been using LINQ recently. But when I come across an interview, I can’t explain:

• What is LINQ?

• Also, is DataSet deprecated due to LINQ?

In terms of interviews, how do I answer these questions?

Answer 1

LINQ is a set of extensions to the .NET platform that allows language integrated queries. This basically means that we can use the same type of syntax to query any dataset — be it an SQL database, Active Directory or XML file — we can use the same syntax to execute queries.
