How can I improve the performance of Entity Framework?
There are several strategies to enhance Entity Framework performance, such as using compiled queries, optimizing your database schema, and reducing the number of database calls.
What are compiled queries and how do they help?
Compiled queries are pre-compiled SQL queries that can be reused, which reduces the overhead of query compilation and improves performance.
Can you give me an example of how to use a compiled query?
Sure! You can define a compiled query like this: var compiledQuery = EF.CompileQuery((MyContext ctx, int id) => ctx.Entities.FirstOrDefault(e => e.Id == id));
Then, you can execute it with your context.
What about lazy loading? Should I use it?
Lazy loading can be convenient, but it may lead to performance issues due to multiple database calls. It's often better to use eager loading when you know you'll need related data.
