title: Cannot implicitly convert type 'void' to 'System.Collections.Generic.Dictionary<string,bool>
body: <p>This code works fine </p>
  
  <pre><code>Dictionary&lt;string, bool&gt; test = new Dictionary&lt;string, bool&gt;();
          test.Add("test string", true);
  </code></pre>
  
  <p>The following code throws this error : Cannot implicitly convert type 'void' to 'System.Collections.Generic.Dictionary</p>
  
  <pre><code>Dictionary&lt;string, bool&gt; test = new Dictionary&lt;string, bool&gt;().Add("test string", true);
  </code></pre>
  
  <p>why? what is the difference?</p>
