As you know LINQ provides a common query syntax to query any data source and ADO.NET allows you to execute query against any RDBMS like SQL Server, Oracle etc. In this article, I am sharing my view on LINQ and ADO.NET.

LINQ to SQL
It is a part of .NET Framework since .NET Framework 1.0

It has full type checking at compile-time and IntelliSense support in Visual Studio, since it used the .NET Framework languages like C# and VB.
