  Hi
   I'm trying to retrieve only current object ,not including children objects:
  
              FetchStrategy fetchStrategy = new FetchStrategy();
              fetchStrategy.MaxFetchDepth = 1;
              fetchStrategy.MaxResultsLimit = 1;
              dbContext.FetchStrategy = fetchStrategy ;
  
              IEnumerable<Sample> samples = dbContext.Sample.Where(s => s.SampleBarcode == sampleBarcode);
  
  but result includes many children object,such as Sample.SampleItem ...
  
  Tell what should I do .
  
  Thanks
  Dgyang

  Hello Yang,
  

  Initially only the current object is being retrieved. If you try to access some of the navigation members of this object, additional calls to the database will be made in order to retrieve the necessary information for them. This means that the navigation members are loaded on-demand.
  Hope that helps.

  Kind regards,
