I have a couple of business-related domains like Purchase, Marketing and Economy. Having the models arranged into a namespace* for each domain would be nice, but there are some entities cutting across domains, like an Item. How to organize those cross-cutting objects?
* = As in C#/Java/Python namespaces.
Since you have the concept of Bounded Context, you should not share domains between the namespaces. Actually, you should have one Item for each namespace that requires it, and each of those Item should have it's own fields as required by the context it is included.
As Eric Evans said, it is not a big deal replicate data in order to never share the same domain between contexts, but only data.

I thought I understood what was happening here, but now I'm seeing some weird behavior that's making me question my understanding of C#'s namespace scoping behavior.

The problem is that in your Update method, all the compiler knows is _context is of type IBusinessEntityContext and the compiler has no idea that _context has type DbContext somewhere in its inheritance tree.

When you are working with namespaces you must fully qualify each class unless it's a child of the current namespace. As such the FluentPDO is probably on the root namespace which means you need to access it like such: self::$_instance = new \FluentPDO(new \PDO("mysql:host=8273639.mysql.rds.aliyuncs.com;dbname=db", 'name', 'password')); ...

From the implementation point of view. You may write the code as: var assistant = GetAssistant(Id); var therapist = GetTherapist("[email protected]"); therapist.ManagedBy(assistant); repository.Save(therapist); The therapist knows if he/she is managed by an assistant, so the rule is applied here. And the therapist can handle concurrency contention with locks. On the other...

It seems to me that your main application namespace is TreeViewTestC and not MyNameSpace.
