How can I optimize my LINQ queries in ASP.NET Core?

To optimize LINQ queries in ASP.NET Core, consider using methods like AsNoTracking for read-only queries, and ensure you're using efficient filtering and projection.

What is AsNoTracking and when should I use it?

AsNoTracking is a method that tells Entity Framework not to track changes to the entities returned by the query. Use it for read-only scenarios to improve performance.

Can you give me an example of a complex LINQ query?

Sure! Here's an example: var result = context.Orders.Where(o => o.Total > 100).Select(o => new { o.Id, o.Customer.Name }); This retrieves orders with totals over 100 and selects the order ID and customer name.

How can I handle null values in my LINQ queries?

You can use the null-coalescing operator ?? to provide a default value or use the Where method to filter out nulls before processing.
