I'm using the WCF Rest service application project template in visual studio. I'm just learning about REST, and I was wondering how I would post a SampleItem object to the following method:

[WebInvoke(UriTemplate = "", Method = "POST")]
public SampleItem Create(SampleItem instance)
{
   // TODO: Add the new instance of SampleItem to the collection
   throw new NotImplementedException();
}

I get the general concepts of gets for the purposes of grabbing data, but I'm not sure how I would post the object in code (or just through a browser for testing) to the service.
