I have a LINQ statement like this:

var media = (from p in postService.GetMedia(postId)
             select new
             {
                 PostId = postId,
                 SynthId = p.SynthId
             });

There are many(possibly thousands) of records returned with the same SynthId. I want to select one one, any random one. So when I'm finished, media should contain records with distinct SynthId.

SynthId can be null, I want all nulls to be in media (the distinct should not affect them). My DAL is EntityFramework, if that will help.

How do I accomplish this in the most efficient way?
