LINQ

LINQ (Language Integrated Query) is a set of features in .NET that adds native data querying capabilities to C# and Visual Basic .NET languages. It allows developers to write queries directly in their code using a SQL-like syntax or method syntax to query various data sources such as collections, databases, XML, and more. LINQ provides a consistent model for working with data across different types of data sources and formats.

Also known as: Language Integrated Query, LINQ to Objects, LINQ to SQL, LINQ to XML, Linq

Why learn LINQ?

Developers should learn LINQ when working with .NET applications to simplify data manipulation and querying tasks, as it reduces boilerplate code and improves readability. It is particularly useful for querying in-memory collections, databases via Entity Framework, and XML documents, making it essential for data-intensive applications in C# or VB.NET. LINQ enhances productivity by enabling declarative querying that integrates seamlessly with the language.
