    <p>If I'm reading this correctly, the problem is expected via dbcontext or objectcontext.</p> <p>FIrst I want to look at your last set of examples ..no abstraction. When you attach a graph to a context, everything in the graph is attached as Unchanged. Period. The context doesn't care how you added or attached "children" to the root (e.g. siblings to a foo) before the context had ANY knowledge of them. If the foo was aalready known by the context and THEN you ADD, then the context is aware of HOW you did the linking..you said "ADD" so it marks them as Added and they'll get inserted.Even if the root is not new. You'ld have to change its state to "Unchanged". But in your case, you are taking a disconnected graph and attaching it, so everyting in the graph is seen as unchanged. You have to explicitly change the state of each of the siblings to what you want for SaveChanges to notice it needs to INSERT.</p> <p>Now to your repository. I have no idea wtf is up with the negative numbers. :) And I don't have time to experiment with that. (curious how that's tricking savechanges, but it's a smelly hack :) ) It depends on what's happening behind your FooRepository query. If that returned foo is beingi tracked by the context, then I would <em>expect</em> that when you ADD siblings, the context will know they are added and will create an insert. But if it is not being tracked, then when you ADD the siblings, context is not there to know about "ADD". At whatever point you reattach the graph (foo + its siblings) to a context, they are all going to be "UNchanged" so you're not getting the desired insert.</p> <p>This is all dependent on a GUESS at whatever else is going on in your repository and what, if any, affect the automapper has. I am guessing that you are doing all of the owrk before the context is aware of the graph so in the end , I think you're calling ATTACH which would result in no INSERTS being sent to the db.</p>

    1. COThanks for your feedback Julie. The problem was actually on my EntityBase object. I overrode the GetHashCode method and was returning the HashCode on the ID itself...so the Hashcode of 0 is always equal. Once I commented that out, everything is firing together through the root. I agree 100% the negative numbers is a bit hackish.

Querying!

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.
