Ok, looking at a baseProduct the ProductListLinks seems to be deprecated  
with the following message:

`"Membership of the Base Product in ProductList need to be handled in ProductList. List of linked product lists could be retrieved by calling ProductListService.GetByBaseProduct."`

Looking at the ProductListService it doesn’t appear to have any extensionmethods called GetByBaseProduct.

Any chance you can provide an example of how this can be done?

Mvh
