Major - P3 Consider the following implementation:
public class Foo { public ObjectId Id { get; set; } public string Name { get; set; } } public class Bar { public ObjectId Id { get; set; } public ObjectId FooId { get; set; } [BsonIgnore] public Foo Foo { get; set; } }
When saving a Bar instance into the Collection the Foo property is ignored as expected. But the property is also being ignored when deserializing Bar.
return await db.GetCollection<Bar>("Bar") .Aggregate() .Lookup("Foo", "FooId", "_id", "Foo") .Unwind("Foo") .As<Bar>() .ToListAsync(cancellationToken);
The code above does not work since the driver is ignoring the property Foo of Bar's class.
'Element 'Foo' does not match any field or property of class Bar.'
Why [*BsonIgnored*] is being used in deserialization?
Interestingly, if a change the Bar class as following (using ShouldSerialize method) the code works as expected:
public class Bar { public ObjectId Id { get; set; } public ObjectId FooId { get; set; } public Foo Foo { get; set; } public bool ShouldSerializeFoo() { return false; } }
Any thoughts on that?
