title: How to modify a KeyValuePair value?
body: <p>I got a problem when I try to modify the value of an item because its only a read only field.</p>
  
  <pre><code>KeyValuePair&lt;Tkey, Tvalue&gt;
  </code></pre>
  
  <p>I've tried different alternatives like:</p>
  
  <pre><code>Dictionary&lt;Tkey, Tvalue&gt;
  </code></pre>
  
  <p>but there I have the same problem. Is there a way to set the value field to an new value?</p>
