Question

Given an EntityType, such as “Contact”, how can I derive from it the name of the EntitySet it would belong to, i.e. the pluralization such as “Contacts”?

Answer 1

If you already have an attached entity (obviously you don’t need the first line, just use your existing entity):

  Contact c = context.Contacts.Where(x => x.blah).FirstOrDefault();
  string setName = c.EntityKey.EntitySetName;

Or if you don’t:

 string className = typeof(Contact).Name
 var container =   
    context.MetadataWorkspace.GetEntityContainer(context.DefaultContainerName, DataSpace.CSpace);
    string setName = (from meta in container.BaseEntitySets
                                          where meta.ElementType.Name == className
                                          select meta.Name).First();
