Entity Framework Tracking vs. No-Tracking No-tracking queries
Example
- No tracking queries are useful when the results are used in a
read-onlyscenario - They are
quicker to executebecause there is no need to setup change tracking information
Example :
using (var context = new BookContext())
{
var books = context.Books.AsNoTracking().ToList();
}
With EF Core 1.0 you are also able to change the default tracking behavior at the context instance level.
Example :
using (var context = new BookContext())
{
context.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.NoTracking;
var books = context.Books.ToList();
}
