How can I perform batch operations using Entity Framework in C#?

You can use the AddRange, UpdateRange, and RemoveRange methods for batch operations in Entity Framework.

Can you show me an example of using AddRange?

Sure! Here's a simple example:

var newEntities = new List<MyEntity> {
    new MyEntity { Name = "Entity1" },
    new MyEntity { Name = "Entity2" }
};

context.MyEntities.AddRange(newEntities);
context.SaveChanges();

What about updating multiple records at once?

You can use UpdateRange like this:

var entitiesToUpdate = context.MyEntities.Where(e => e.Condition).ToList();
foreach (var entity in entitiesToUpdate) {
    entity.Property = newValue;
}
context.UpdateRange(entitiesToUpdate);
context.SaveChanges();

Are there any performance considerations I should be aware of?

Yes, batch operations can improve performance by reducing the number of database round trips. However, be cautious with very large batches as they may lead to memory issues.
