What is the recommended way to do DDD Value Objects in EF Core?

[rantri]

Hi,

In @JeremyLikness blog post: "The Plan for Entity Framework Core 6.0" there is a section about Domain-Driven Design Value Objects:

In EF6 I used Complex Types for value objects. I thought that owned entities is the way to do ValueObjects in EF Core.
Owned entities is the approach recommended in: ".NET microservices - Architecture e-book".

Why owned entities are not a good fit?
What is the recommended way to implement Value Objects?

Thank you all for a great product.

@rantri See value object examples. Unfortunately, issues to make this better (#9906 and #13947) had to be punted out of 6.0.

Owned types are not a good fit because they have keys, even though the key might be hidden. This results in non-obvious behaviors when value objects are used as if they did not have keys. See this comment and the linked issues for some more discussion.
