Currently there is an issue when projecting collection of primitives from JSON entities (specifically, nested ones) - problem is in shared type expanding visitor - we don't correctly handle includes that the JSON type gets expanded to - in case of other navigations we can successfully bind them, in case of primitive non-collections we just ignore them (the includes), but in case of collection of primitives we leave them as they are but fail to reason about them correctly in the translation phase.
example
ss.Set<JsonEntityBasic>()
.OrderBy(x => x.Id)
.Select(x => x.OwnedCollectionRoot
.Where(xx => xx.Name == "Foo")
.Select(xx => new { xx.Names, xx.Numbers })
.ToList())throws:
