title: Generic List .First not working LINQ
body: <pre><code>        var stuff = ctx.spReport();
          var StuffAssembled = new List&lt;ReportCLS&gt;();
          var val = new List&lt;ReportCLS&gt;();
          foreach (var item in stuff)
          {
              StuffAssembled.Add(new ReportCLS(item));
  
          }
  
          val.Add(StuffAssembled.First());
  </code></pre>
  
  <p>Keeps throwing </p>
  
  <p>System.Collections.Generic.List' does not contain a definition for 'First' and no extension method 'First' accepting a first argument of type 'System.Collections.Generic.List' could be found (are you missing a using directive or an assembly reference?)</p>
  
  <p>what is going wrong ?</p>
  
  <p>moreover how do i fix it?</p>
  
  <p>Thanks</p>
