title: 'RestClient' is a namespace but its used like a type - package issue
body: <p>Ive removed sensitive data but am getting this issue when trying to make an API request, although I have the relevant packages installed. Why would this be?</p>
  <pre><code>using System;
  using IronXL; 
  using RestClient;
  using Rest;
  using Newtonsoft;
  using RestSharp;
  using RestSharp.Authenticators;
  using RestSharp.Validation;
      public static void APIRequest()
          
      {
          var client = new RestClient(&quot;&quot;);
          client.Timeout = -1;
          var request = new RestRequest(Method.POST);
          request.AddHeader(&quot;Accept&quot;, &quot;application/vnd.evolutionx.v1+json&quot;);
          request.AddHeader(&quot;Authorization&quot;, &quot;Bearer  &quot;);
          request.AddHeader(&quot;Content-Type&quot;, &quot;application/json&quot;);
          IRestResponse response = client.Execute(request);
          Console.WriteLine(response.Content);
  
      }
