The drive does not fetch entities along navigation relationships about linqpadodata4

Driver has a method .Expand(...). You can use it like

Products.Expand(product => product.Supplier).ToList();

Thanks. Is there a way to force it to use urls of the form

Product(3)/Supplier 

rather than

Product?$expand=Supplier

I need this because the relationship is defined in the OData model, but not in the Product CLR type on the server side. My controller does have a GetSupplier method would provide the related supplier.

Sure,

Products.Where(p => p.ID == 3).Select(p => p.Supplier).Single()

Thanks. That does use the Product(3)/Supplier URL when the Product class has a property called Supplier. However, in my real application where I am building up the EDM model manually and adding the navigational property manually without having the Supplier property, LinqPad only makes a call to Product(1). Any ideas? Here is the code I am using to build the EDM model relationship.

EdmNavigationPropertyInfo info = new EdmNavigationPropertyInfo();
            info.Name = relationshipName;
            info.Target = sourceEntityType;
            info.TargetMultiplicity = EdmMultiplicity.Many;
            EdmNavigationProperty navigation =
            sourceEntityType.AddUnidirectionalNavigation(info);
            sourceEntitySet.AddNavigationTarget(navigation, targetEntitySet);

Correct me: Your model has one Product entity set, two entity definitions Product and Supplier and the Product entity has an Supplier property. And there is no Supplier entity set?
