Answer 1

As far as I remember, they are just generated so that you can use the data contracts used in the service as object data sources for data binding against UI controls.

Answer 3

I was able to delete them from one of our projects. Project built fine, and loaded stuff from the database fine, so I'm assuming it was safe. I would like to hear someone who knows more about them weigh in on this element of the subject though.

Answer 4

Expand your Reference.svcmap from visual studio.

Update reference.

And delete yellow warning datasources.
