Hello,
An item can be associated to more than one category. But how do I get the list of categories of an item? The .NET SDK only exposes a single CategoryId for an item. Is there a way to access the list of categories of an item?
Thank you

When you SearchCatalogObjects or BathRetrieveCatalogObjects you can set include_related_objects to true to include all the categories associated to catalog objects. 
@Bryan-Square I have an example where only one category is returning in the related objects field but there are two IDs being returned for category in the objects field
When I go to map the ID to the related objects not all categories are being returned. This is for SearchCataLogObjects
I found the bug on Square’s side. The relatedObject is only returning categories if they appear on an item as a “reporting category” but not all categories mapped to an item. Looks like the graphql code on Square’s side needs to be updated to return relatedObjects from a merge of categories and reporting categories
