Unable to determine the serialization information for c => Convert(c).Id

XMLWordPrintableJSON

      Since we went from version 2.0.1 to 2.1.0 we get this error: Unable to determine the serialization information for c => Convert(c).Id

      Here's the exception:

      System.AggregateException : One or more errors occurred.
  ----> System.InvalidOperationException : Unable to determine the serialization information for c => Convert(c).Id.

      Here's the object structure:

      public interface IContent {
  int Id { get; }
}

public class News : IContent {
  public int Id { get; private set; }
}

public abstract BaseRepository<T> where T : IContent {
  public async Task<List<T>> GetByIdsAsync(IEnumerable<int> ids) {
    var filter = Builders<T>.Filter.In(c => c.Id, ids);
    return await GetCollection()
                      .Find(filter)
                      .ToListAsync();
  }
}

      Here are the conventions:

      BsonClassMap.RegisterClassMap<News>(cm => { cm.AutoMap() });
