Body
In this simple example, I have two entities: Event and Address. I have a console application running every night to import event data from an XML source and add it to my database. As I loop through the XML event nodes (inside of the Entity Framework context), I check to see if there is an address record with the given values already in the database. If not, it adds a new record. <pre><code>using (DemoContext context = new DemoContext()) { foreach (XmlNode eventNode in eventsXml.SelectNodes("/Events/Event")) { Event newEvent = new Event(); newEvent.Title = **get from XML** Address address = context.Addresses.Where(a => a.Title.Equals(title, StringComparison.OrdinalIgnoreCase) && a.Address1.Equals(address1, StringComparison.OrdinalIgnoreCase) && a.Address2.Equals(address2, StringComparison.OrdinalIgnoreCase) && a.City.Equals(city, StringComparison.OrdinalIgnoreCase) && a.State.Equals(state, StringComparison.OrdinalIgnoreCase) && a.ZipCode.Equals(zipCode, StringComparison.OrdinalIgnoreCase) ).FirstOrDefault(); if (address != null) newEvent.Location = address; else { newEvent.Location.Title = title; newEvent.Location.Address1 = address1; newEvent.Location.Address2 = address2; newEvent.Location.City = city; newEvent.Location.State = state; newEvent.Location.ZipCode = zipCode; } context.Events.Add(newEvent); } context.SaveChanges(); } </code></pre> I know it is slower performance to call context.SaveChanges() after every event, so I would like to do this all at the end (or do it in batches but that's not relevant to this problem). However, when I query against context.Addresses, it doesn't seem to be aware of any new addresses until after I call context.SaveChanges() so I get duplicate records. For my purposes it may be okay to save after each record rather than at the end, but I would like to know if there is a good, simple alternative.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
