What methods can be used to improve data reading efficiency with Entity Framework Core?

To improve data reading efficiency in Entity Framework Core, the following methods can be applied:

• Using projections (Select) — select only the necessary fields to reduce the amount of data transmitted.
• No tracking (AsNoTracking) — if the data is read-only, this speeds up queries.
• Eager loading (Include) — load related entities with a single query to avoid the N+1 problem.
• Filtering and pagination — limit data volume using Where and Skip/Take.
• Query compilation (Compiled Queries) — for repeatedly executed queries.

Example of using AsNoTracking and projection:

var users = context.Users
    .AsNoTracking()
    .Where(u => u.IsActive)
    .Select(u => new { u.Id, u.Name })
    .ToList();
