IConceptualModelConvention<NavigationProperty>

Not sure if it will be implemented or not in EF7 but it's a nice feature in eF6.

We use this class to customize the use of EF6 and it saves a lot of work in a huge domain (200+ entities):

public class CustomDatabaseConventions :
    Convention,
    IConceptualModelConvention<NavigationProperty>
{
    public ConvencoesDatabase()
    {
        this.Types().Configure(t => t.SetCustomSchema());

        this.Properties().Configure(p => p.HasColumnName(p.ClrPropertyInfo.Name.ToLower()));
    }

    public void Apply(NavigationProperty property, DbModel model)
    {
        var clrPropertyInfo = property.MetadataProperties["ClrPropertyInfo"].Value as PropertyInfo;
        if (clrPropertyInfo.GetCustomAttribute<CustomCascadeDeleteAttribute>() != null)
            property.FromEndMember.DeleteBehavior = OperationAction.Cascade;
    }
}

Hey Max,

We have #214 tracking the need to be able to create custom conventions. Metadata is a lot simpler/easier in EF7, so the API for custom conventions will be different. It may even just be a hook to manipulate the metadata model at different points in the pipeline. The scenarios you listed will be possible (and probably simpler).
