I'm developing an app for a client that will read and write Google contacts from a WinForms app. I found this site:
http://code.google.com/apis/contacts/docs/2.0/developers_guide_dotnet.html

When I run my code, I am able to return a list of contacts, and I can write new contacts to Google, and I can delete a contact also.

My issue is that when I go to my Contacts page in Google there are fields on the screen that I can't seem to find in the Contact class, and there are fields such as Summary and Author that don't seem to appear anywhere in the contact page in Google.

Another thing I can't see to find - is there a unique Id of some kind on a Google Contact?

I'm wondering of anyone has any experience doing this as I could use some help.

Thanks!
