      Summary

      LinqProvider V3 failed to materialize a C# projection object (defined class, not an anomymous class) from a C# source object with an ObjectId string serializer : An error occurred while deserializing the Id property of class ConsoleApp.Projections.IdObjectBase: Cannot deserialize a 'String' from BsonType 'ObjectId'.

      Tested with MongoDb driver 2.17.1 and 2.15.1 over local MongoDb instance.

      How to Reproduce

      See C# .Net6 attached project that reproduces the error.

      Additional Background

      ObjectId deserialization is working as expected when using LinqProvider.V2.

      I really think that deserialization MUST use the C# source object serialization configuration over the projection.

      Please note that it is working fine (and as expected) when using an anomyous object for projection with LinqProvider.V3.
