Distinct by both Key and Value:

var results = source.Distinct().ToList();

Distinct by Key or Value (just change the property on GroupBy call:

var results = source.GroupBy(x => x.Key).Select(g => g.First()).ToList();

You should use a Set (of pair objects) if you wish to have distinct pairs or a Map/Dictionary if you wish to have distinct keys.
