    1. COI'm trying to figure this out myself, but I don't *think* you can pass the fileContents in via the UriTemplate. I *think* you either have to use Silverlight/Flash or send the File Contents up via an HTML Form. If you send the contents up via an HTML Form, I think you have to acquire or implement a Multipart Form Parser to use in your WCF Service as demonstrated in both of these posts: http://stackoverflow.com/questions/9734941/upload-file-from-html-form-multipart-form-data-to-wcf-rest-service-as-a-stream or http://antscode.blogspot.com/2009/11/parsing-multipart-form-data-in-wcf.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
