What are the best practices for using LINQ in ASP.NET Core?

Some best practices include using IQueryable for deferred execution, avoiding loading unnecessary data, and using projection to select only the needed fields.

Can you explain why deferred execution is important?

Deferred execution allows LINQ queries to be executed only when the data is actually needed, which can improve performance and reduce memory usage.

What are some common mistakes to avoid with LINQ?

Common mistakes include executing queries multiple times unnecessarily, not using AsNoTracking for read-only queries, and failing to handle exceptions properly.

How can I optimize LINQ queries for large datasets?

You can optimize LINQ queries by using pagination, filtering data at the database level, and leveraging indexes in your database.
