    <p>From a point of view of <em>clean</em> creation of POCO entities, there is no difference between the two generators. Both generators produce the same entities, however, ADO.NET POCO Entity Generator is based on <code>ObjectContext</code>'s API, whereas ADO.NET <code>DbContext</code> Generator is based on <code>DbContext</code>'s API.</p> <p>DbContext's API has a few very nice new features (Local, Query on navigation property, etc.) and API is somehow simplified but at the same time it looks like some features used in ObjectContext API are missing in DbContext API (or at least it has not been explored enough yet). </p> <p>EF 4.1 RC is go-live release. It means that you can build a real application with it because API will not change in RTW (only bugs will be fixed). Also RTW should be in the next month so I think you will not be ready with your application before the final version is shipped.</p> <p><code>ObjectContext</code> API or <code>DbContext</code> API? <code>ObjectContext</code> API is much better covered by documentation and blog posts. You can find plenty of examples about it. Also its limitations are already well known. <code>DbContext</code> API is new release. A very promising release, mostly because of the code-first approach. There is still a very limited number of blog posts, no book and the API is not proven enough. So it depends if you are ready to fight with new API? If not, then <code>ObjectContext</code> API is still a good choice because you don't need the code-first approach.</p>

    2. CO@Danny: `DbSet` has `Local` property which allows you easily querying already loaded entities without new query to database.

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.
