How to avoid using List<List<T>>?
<p>I have a WCF service that i cannot touch which returns <code>List&lt;FilesWithSettings&gt;</code>. 
I need to enter few PC which are grouped together and retrieve <code>List&lt;FilesWithSettings&gt;</code> for each one along with <code>PCIdentifier</code> which brings me to <code>Dictionary&lt;PCIdentifier,List&lt;FilesWithSettings&gt;&gt;</code> or <code>List&lt;PCIdentifier&gt;</code> and <code>List&lt;List&lt;FilesWithSettings&gt;&gt;</code> which isn't elegant and unreadable.</p>

<p>Can you give me more elegant solution ?</p>
