title: Publishing a knowledgebase via QnAMaker v4 API
body: <p>I'm attempting to migrate my bot from QnAMaker v2 API to QnAMaker v4 API. I am able to send updates to the knowledge base, but the publish doesn't seem to take. Here's the code I'm using.</p>
  
  <pre><code>    static void Main(string[] args)
      {
          MainAsync(args).Wait();
      }
  
      static async Task MainAsync(string[] args)
      {
          Console.WriteLine("We're starting.");
          var client = new HttpClient();
          client.DefaultRequestHeaders.Add("Ocp-Apim-Subscription-Key", mySubKey);
          var uri = new Uri($"https://westus.api.cognitive.microsoft.com/qnamaker/v4.0/knowledgebases/{myKBId}");
          var payload = "{\"add\": {\"qnaList\": [{\"id\": 0,\"answer\": \"A woodchuck could chuck all the wood he could chuck if a woodchuck could chuck wood.\",\"source\": \"Custom Editorial\",\"questions\": [\"How much wood could a woodchuck chuck if a woodchuck could chuck wood?\"],\"metadata\": []}]},\"delete\": {},\"update\": {}}";
          var method = new HttpMethod("PATCH");
          var request = new HttpRequestMessage(method, uri);
          request.Content = new StringContent(payload, Encoding.UTF8, "application/json");
          var response = await client.SendAsync(request);
          var responseMessage = await response.Content.ReadAsStringAsync();
          Console.Write(responseMessage);
          Console.ReadLine();
          method = new HttpMethod("POST");
          payload = "";
          request = new HttpRequestMessage(method, uri);
          request.Content = new StringContent(payload, Encoding.UTF8, "application/json");
          response = await client.SendAsync(request);
          responseMessage = await response.Content.ReadAsStringAsync();
          Console.WriteLine(responseMessage);
          Console.ReadLine();
  
      }
  </code></pre>
  
  <p>My test process is </p>
  
  <ol>
  <li>Ask the bot about woodchucks.</li>
  <li>Run this code.</li>
  <li>Verify the q/a pair about woodchucks is in the knowledge base.</li>
  <li>Ask the bot about woodchucks again.</li>
  </ol>
  
  <p>So far the api responds as expected, but my bot remains oblivious to critical woodchuck knowledge until I click publish on the qnamaker.ai site. What am I missing?</p>
