Is it possible to enable OData with an entity model created using the Code First method.
I can't see anything in the documentation other that enabling OData using the Model or Database First method.

Thanks

Hi cseils,
 
Yes, it is possible to enable OData and use Code First entities.
Be sure to decorate your Code First entities with the IgnoreProperties and DataServiceKey attributes:
 
[IgnoreProperties(@"EntityAspect", @"AAAA_EntityAspectForSerialization")]
[DataServiceKey(@"MyEntityID")] // where MyEntityID is the entity's key
 
Other than that, you will need to follow steps 2 and 3 described in the  http://drc.ideablade.com/xwiki/bin/view/Documentation/odata-enable#HEnablingOData - Enabling OData topic in the http://drc.ideablade.com/xwiki/bin/view/Documentation/odata-enable#HEnablingOData - DevForce Resource Center .
Also, you might want to implement System.Data.Services.IUpdatable to support OData updates.
 
Regards,
