title: YouTube Data Api v3 in C#
body: <p>I am learning to use YouTube Data Api v3 in C#. What I want to do is to manage YouTube Playlists (Create, Delete, Update). I want it to be a console project. I used the sample playlist code given <strong><a href="https://developers.google.com/youtube/v3/code_samples/dotnet" rel="nofollow noreferrer">here</a></strong>. I've used the Create Playlist Code but when I run it it shows me the following 
  Error:</p>
  
  <blockquote>
    <p>The redirect URI in the request, 127.0.0.1:52222/authorize/, does not
    match  the ones authorized for the OAuth client. To update the
    authorized redirect  URIs, visit: &lt;...></p>
  </blockquote>
  
  <p>The project is in initial faces. Can anyone guide me? I don't know what is the problem.</p>
