OData v4 Attribute Routing

Hi,

I'm building an OData v4 service with Web-Api 2.2. I have the following routes:

/Products
/Products('id')
/Products('id')/Orders
/Product('id')/Orders('id')

And I would like to have the following controllers/actions for them:

class ProductsController 
{
    [ODataRoute("/Products")]
    public IQueryable<Product> Get() {}

    [ODataRoute("/Products({id}")]
    public SingleResult<Product> Get(int id) {}
}

class OrdersController 
{
    [ODataRoute("/Orders")]
    public IQueryable<Order> Get() {}

    [ODataRoute("/Orders({id}")]
    public SingleResult<Order> Get(int id) {}

    [ODataRoute("/Products({id})/Orders")]
    public IQueryable<Order> GetByProduct(int productId) {}


    [ODataRoute("/Products({productId}/Orders({id})")]
    public SingleResult<Order> GetByProduct(int id, int productId) {}
}

This is my config section in WebConfigApi.cs

ODataModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Product>("Products");
builder.EntitySet<Order>("Orders");
var route = config.MapODataServiceRoute(
   routeName: "ODataRoute",
   routePrefix: null,
   model: builder.GetEdmModel());

But I'm getting errors about invalid OData routes. I was under the impression that when I use attribute routing I can use any action name and parameters that I like and I can organize my controllers/actions the way I want but that does not seem to be the case. Are my assumptions wrong?

Thanks
