Accepted answer
You can group items by the key, and then select what item from the group you want to use as value. I use FirstOrDefault as an example:
... .Select(c => new SampleClass { Id = c.Location.Name, Name = c.Location.Name })
.GroupBy(c => c.Id)
.Select(group => group.FirstOrDefault())
.ToList()

Is this what you need: http://sprokhorenko.blogspot.com/2009/11/convenient-distinct.html ?
This is an extension for IEnumerable that allows you to .Distinct() for any field (or even several ones using lambdas), which creates IEqualityComparer for you on the fly.
