thank you so much
so you have only navigation property. no other properties right?
Yes
According to my point of view xxx.HttpApi.Client module is in the infrastructure layer(maybe not, I am not sure. What do you think about that?) can I add it here too? Another alternative way,as you told, is to add a new abp module project that is in the infrastructure layer to the solution. Which one is the best?
Thank you for your answer but I would like to expand my question. For blob provider, I must to add some package(Google.Cloud.Storage.V1) from nuget. Would it be correct to add these packages to this layer? I am hesitant as to whether it would be correct to add these packages to this layer.
