The best way to find which name of your service is access url /api/AbpServiceProxies/GetAll?type=angular you will find all services.
Great question,
Hikalkan you don't answered about save a Complex Graph or Hierarquical Graph.
As i know the EfRepositoryBaseOfTEntityAndTPrimaryKey handle only with main Entity.
If i want update association entites( complex Graph), how can i do?
If i have a disconnected object the only way your offer is comparing Id.
What if EfRepositoryBaseOfTEntityAndTPrimaryKey could handle with complex Graph using ObjectState, what your opinion about this?
