Step-by-step explanation:
The two main ideas of LINQ (Language Integrated Query) are querying and transforming data.
Querying refers to the ability to retrieve specific data from a data source based on certain criteria. For example, you can use LINQ to query a collection of numbers and retrieve only the even ones.
Transforming involves the manipulation and modification of data. With LINQ, you can transform data by applying various operations such as sorting, filtering, grouping, and projecting.
