Entity Framework Code First ReadOnly Collections

Question

As a new to Entity Framework, and already having developed almost all classes with the ReadOnly collections, my question is:

Is there a way to use ReadOnly collections with Code First?

OR

Should ReadOnly collections be used with Code First?

Answer 1

No there is not way to use read only collections with EF because even during materialization of entities read from database EF must fill that collection with entities or assign writable collection to your navigation property.
