I have a simple Person }}class with an array of {{{}Addresses:

 
public class Person
{{{}}
  public Guid Id { get; set; }  
{{  public string? FirstName { get; set; }}}
{{  public string? LastName { get; set; }}}
{{  public IEnumerable<Address>? Addresses { get; set; }}}
}

public class Address
{{{}}
{{  public string? Street { get; set; }}}
{{  public string? City { get; set; }}}
{{  public string? ZipCode { get; set; }}}
}
I've mapped the entities as so:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{{{}}
  modelBuilder
    .Entity<Person>()
    .ToCollection("Person")
    .OwnsMany(x => x.Addresses);
}
I successfully write data out using EF:

{{{}}
  "_id": {
    "$binary": {
      "base64": "CbUTuW9pXkC3Vlmkesu1Fg==",
      "subType": "03"
{{    }}}
  },
  "FirstName": "Bob",
  "LastName": "Smith",
  "Addresses": [
    {
      "City": "Denver",
      "Street": "123 Main St.",
      "ZipCode": "80401"
    },
    {
      "City": "Los Angeles",
      "Street": "246 Beach Dr.",
      "ZipCode": "90210"
{{    }}}
  ]
}

When I try a simple query:

 
public IQueryable<Address> GetPersonData()
{{{    }}
  var data = _dbContext?.Person.SelectMany(x => x.Addresses).Take(10);
    return data;
}
The follow exception is thrown:

System.ArgumentException: Field 'Microsoft.EntityFrameworkCore.Query.TransparentIdentifierFactory+TransparentIdentifier`2[db_editor_api.Models.Person,db_editor_api.Models.Address].Inner' is not defined for type 'db_editor_api.Models.Person'

This is as simple an operation as we can get in terms of working with embedded documents and should work seamlessly.
