Crystal with VS2005 Dataset NO field explorer

Have ASP.NET web app using VS 2005 and Crystal. I am using typed dataset and having issue with seeing filed in field explorer

did following in seperate class
-created dB connection
-cretaed typed dataset
-added Crystal Report to project

now, in report when go to database expert I see following

/project data /ADO.NET DataSets
...no items found
/project data / .Net Objects
populateDataset 'class name
populateDataset


here are my questions

1.) Should I be seeing item under /project data /ADO.NET DataSets ? anything wrong ?

2.) if I select populateDataset as my data source, I do not see any fields that I can select from.

Any help would be deeply appreciated.

thanks,
Shyam
