Hi, I think this is not working anymore.
I think it has to do with the latest OData changes on microsoft.
Or maybe it just works for the Blazor Server version.. which I guess would use linq include instead.
I think it's related to this How do I expand to second level - #4 by korchev
so my guess is we should use the dot notation for Blazor Server and the nested ($expand..) notation for ODATA sources
