Entity Framework Tracking vs. No-Tracking Tracking queries
Example
- By default, queries that return entity types are tracking
- This means you can make changes to those entity instances and have
those changes persisted by
SaveChanges()
Example :
- The change to the
bookrating will be detected and persisted to the database duringSaveChanges().
using (var context = new BookContext())
{
var book = context.Books.FirstOrDefault(b => b.BookId == 1);
book.Rating = 5;
context.SaveChanges();
}
