    <p>I have a model with the following structure where I have lists of Codes that can be used within the system. </p> <p>There is a one to one relationship between a car and an engine so I want the engine details to be mapped to the Car table so an engine is not an entity its just a domain model abstraction. That engine contains a Code that describes the engine Type.</p> <p>My dbcontext has a DbSet for CodeList and for Car as they are the two aggregate roots in the system. When I attempt to map this to the database I get the following error:</p> <p>Each type name in a schema must be unique. Type name 'Code' is already defined. </p> <p>If I remove the Navigation property in the Engine class then the problem goes away but I want to be able to access the Code value without having to look it up independently. If I remove the virtual and attempt to map the id property of the code directly it tells me Code is defined as an entity and may not be redefined as a complex type. I am not sure where I am going wrong with this it seem like a straight forward usage. It looks like Engine is being treated as a Complex Type and therefore cannot have Navigation Properties. </p> <pre><code>CodeList { public int Id {get;set;} public string Name {get;set;} public IList&lt;Code&gt; codes {get;set;} } Code { public int Id {get;set} public string Value {get;set;} } public Car { public int Id {get;set;} public Engine Engine {get;set;} } public Engine { public int Size {get;set;} public int TypeId {get;set;} public virtual Code Type {get;set;} } </code></pre>

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.
