title: GoogleClientSecrets.cs not found youtube api v3
body: <p>I'm trying to upload files on youtube using youtube api v3. I have done everything well but I have one problem. When I'm debugging it vs says that it can't found GoogleClientSecrets.cs and then NewtonsoftJsonSerializer.cs not found. What's wrong? I have already updated <code>Install-Package Google.Apis.YouTube.v3</code> using nuget console.</p>
  
  <p>And I have using </p>
  
  <pre><code>using Google.Apis.Services;
  using Google.Apis.Upload;
  using Google.Apis.YouTube.v3;
  using Google.Apis.YouTube.v3.Data;
  </code></pre>
  
  <p>I'm doing that using <a href="https://developers.google.com/youtube/v3/code_samples/dotnet#upload_a_video" rel="nofollow">this code</a></p>
