{{Further|Language Integrated Query}}
C#s [[Language Integrated Query]] (LINQ) is a set of features designed to work together to allow in-language querying abilities and is a distinguishing feature between C# and Java.

LINQ consists of these features:
* Extension methods allow existing interfaces or classes to be extended with new methods. Implementations can be shared or an interface can have a dedicated implementation.
* Lambdas allow for expression of criteria in a functional fashion.
* Expression trees allow a specific implementation to capture a lambda as an [[abstract syntax tree]] rather than an executable block. This can be utilized by implementations to represent criteria in a different language, e.g. in the form of an SQL where clause as is the case with e.g. [[Language Integrated Query|Linq, LINQ to SQL]].
* Anonymous types and type inference supports capturing and working with the result type of a query. A query may both join and project over query sources that may lead to a result type that cannot be named.
* Query expressions to support a syntax familiar to [[SQL]] users.
* Nullable (lifted) types to allow for a better match with query providers that support nullable types, like e.g. [[SQL]].
