Common pitfalls include using inefficient joins, not using deferred execution properly, and failing to filter data early.

Can you give me an example of an optimized LINQ query?

How does indexing affect LINQ query performance?

Indexing can significantly improve performance by allowing the database to quickly locate the data needed for the query.
