How to update related entities using Entity Framework Core

[karamem0]

I am using Beef with Entity Framework Core. I want to create an API that updates related entities like Order and OrderDetails. Pure Entity Framework Core can track child entities when Add or Remove method of relationship property was called, but Beef seems not to be able to track child entities. I think this is caused by AutoMapper mapping Entities to EfModel.
Any good ideas on this?

Are you using the latest version of Beef; i.e. v5 - see previous comments in Issue 94. Extra effort / changes were made to support more advanced EF scenarios, such as what you describe. There is a new sample (including documentation) that demonstrates a parent to many child relationship. There may be scenarios that CoreEx/Beef do not cover; in these instances then standard EF should be used. Latest is also moving away from AutoMapper as difficult to debug, etc.
