I have a project where there are two deployment steps using the same package, when I try to delete one of them then an Error 500 is returned, detail as below
Error: 500 Server error: An error occurred while saving entities that do not expose foreign key properties for their relationships. The EntityEntries property will return null because a single entity cannot be identified as the source of the exception. Handling of exceptions while saving can be made easier by exposing foreign key properties in your entity types. See the InnerException for details.
