- The .NET Language-Integrated Query defines a set of general purpose standard query operators that allow traversal, filter, and projection operations to be expressed in a direct yet declarative way in any .NET-based programming language. These standard query operators will allow queries to run against any IEnumerable datatype. LINQ allows third parties to set up the use of these standard query operators with new domain-specific operators that are appropriate for the target domain or technology. More importantly, Microsoft says, third parties are also free to replace the standard query operators with their own implementations that provide additional services such as remote evaluation, query translation, optimization, and so on. Because LINQ uses all the same standard query operators, if it is implemented correctly will have the same support as the standard query operators. Microsoft uses the term language-integrated query to "indicate that query is an integrated feature of the developer's primary programming languages (for example, Visual C#, Visual Basic). Language-integrated query allows query expressions to benefit from the rich metadata, compile-time syntax checking, static typing and IntelliSense that was previously available only to imperative code. Language-integrated query also allows a single general purpose declarative query facility to be applied to all in-memory information, not just information from external sources."
