How do I optimize my Entity Framework queries in ASP.NET?

To optimize your Entity Framework queries, consider using techniques like eager loading, filtering data at the database level, and using compiled queries.

What is eager loading and how does it help?

Eager loading is a technique that loads related entities as part of the initial query, reducing the number of database calls and improving performance.

Can you give me an example of eager loading in code?

Sure! You can use the Include method like this: context.Orders.Include(o => o.Customer).ToList(); This loads orders along with their related customers.

What about filtering data at the database level?

Filtering data at the database level means applying conditions in your query to retrieve only the necessary data, which reduces the amount of data transferred and processed.
