How can I optimize my ASP.NET Core ORM queries?

To optimize your ORM queries in ASP.NET Core, consider using eager loading, filtering data at the database level, and indexing your database.

What is eager loading and how does it help?

Eager loading is a technique where related data is loaded from the database at the same time as the main entity, reducing the number of queries.

Can you give an example of how to implement eager loading?

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

What about filtering data at the database level?

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