Exception when saving List<string> to Settings
<p>I am trying to save List to settings using the following code. 
I have other controls bound to settings and they work fine, if I comment the first three lines then it seems to work OK, but otherwise I get exception on the save() method</p>

<pre><code>StringCollection playLists = new StringCollection();
playLists.AddRange(getListsToSync().ToArray());
Properties.Settings.Default.PlayLists = playLists;
Properties.Settings.Default.Save(); //exception here..
</code></pre>

<p>I get this exception</p>

<p>Could not load file or assembly 'System.XmlSerializers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.</p>
