NotImplementedException when storing against MemcachedClient in v1.3 client

When performing a simple Store operation against a MemcachedClient however, I get a NotImplementedException

Sample code:

var config = new MemcachedClientConfiguration();
config.AddServer("127.0.0.1", 11219);
var client = new MemcachedClient(config);

var res = client.Store(StoreMode.Set, "key", "value");
Console.WriteLine("result: " + res);

var value = client.Get("key");
Console.WriteLine("value: " + value);
