    <p>In my scenario i've a <strong>MVC</strong> on iis serializing objects from entity framework where i've overridden <em>GetHashCode</em> and <em>Equal</em> methods since <strong>the Id of those objects is immutable once committed to the database.</strong><br> i also have some <strong>client, who can't reach the database</strong>, but connect to iis to get those entities serialized via json and deserialize them locally using newtonsoft.json.<br> When i deserialize them in the clients for a second time, to refresh the data in them, i was expecting the existing instances to be updated automatically.</p> <p>I'm expecting a little too much?<br> Should i write some clone method to copy properties and check a cache for existing ids?<br> Did i wrote something wrong in the <em>Equal</em> and <em>GetHashCode</em> methods?</p> <p>For instance:</p> <ol> <li>I've a blog entity with a title in the database</li> <li>The client connect to iis <ol> <li>get a json string containing {"Id" : 1, "Name" : "blogName"}</li> <li>deserialize it and store it locally</li> <li>add post to the blog in the same way to an observable collection in the class blog i've used client side</li> </ol></li> <li>Someone or something Change the blog name in the database</li> <li>The client try to refresh <ol> <li>get the json string containing {"Id" : 1, "Name" : "newBlogName"}</li> <li>deserialize it to a new instance of class blog, with same id</li> </ol></li> </ol> <p>What's next? copy the new instance name to the old one, ore there's a better way?</p>

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.
