Mastering IQueryable: How to Work Efficiently with EF Queries in .NET
LINQ to EF: Working with IQueryable Objects LINQ (Language Integrated Query) is a powerful technology that allows developers to write SQL-like code in their preferred programming language. Entity Framework (EF) is a popular ORM (Object-Relational Mapping) tool that enables developers to work with databases using .NET objects. In this article, we will explore the relationship between LINQ and EF, specifically focusing on how to work with IQueryable objects.
Understanding IQueryable When you query data from an EF database context using methods like Where, Select, or OrderBy, it returns an IQueryable<T> object instead of a list of objects directly.
