    <p>I'm working with Entity Framework 4.1 in an MVC3 Web Application. I am tasked with re-writing a legacy application with a database w/ approximately 200+ tables, already in place with data, thus taking the Database first approach with EF. </p> <p>I understand that it's bad practice to create one giant edmx model for the entire app, but after hours of research, I can't get a clear direction on how to move forward because I can't figure out how to re-use common tables in more than one model. But I'd like to break up my models into smaller, managable contexts. </p> <p>When I place a common table (such as Users) in two models, the project throws a compilation error in the form of: </p> <blockquote> <p>The type 'Project.Models.EntityX' already contains a definition for 'EntityX_PropertyY'</p> </blockquote> <p>The closest I've found to a workaround was here: <a href="http://connect.microsoft.com/VisualStudio/feedback/details/366721/entity-framework-the-type-xxx-already-contains-a-definition-for-x" rel="nofollow">http://connect.microsoft.com/VisualStudio/feedback/details/366721/entity-framework-the-type-xxx-already-contains-a-definition-for-x</a></p> <blockquote> <p>Posted by Microsoft on 9/17/2008 at 5:18 PM </p> <p>This issue is by design. The work-around is to either put the models in a different folder (for C# &amp; ASP.NET projects), or to set the custom tool namespace (for C# &amp; VB projects). </p> </blockquote> <p>This was back in '08. I couldn't get either option to work, and I'm wondering if there is a better way to go about architecting the project so that I am able to use the same table in more than one model?</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.
