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 is a part of .NET Framework since .NET Framework 3.5
SqlConnection/OleDbConnection is used for database connectivity.

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.
It used T-SQL to query the data to query the database and some other syntax for querying the other data source.
It used LINQ to query the data which provides the uniform programming model (means common query syntax) to query the various data sources.
What do you think?

I hope you will enjoy LINQ and ADO.NET while querying data source. I would like to have feedback from my blog readers. Your valuable feedback, question, or comments about this article are always welcome.
