title: Authenticate with OneDrive SDK in a c# console project
body: <p>I'm trying to create a program that will download all my OneNote files from OneDrive. But when I try to authenticate using <code>msaAuthenticationProvider</code> a white window appears and then nothing happens. I think the window is supposed to be the Microsoft login, but nothing appears in it.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>string[] scopes = new string[] {
      "onedrive.readonly",
      "wl.signin"
  };
  var msaAuthenticationProvider = new MsaAuthenticationProvider(
      clientId,
      returnURL,
      scopes);
  
  await msaAuthenticationProvider.AuthenticateUserAsync();
  var client = new OneDriveClient(URL, msaAuthenticationProvider);
  </code></pre>
  
  <p>It gets to the AuthenticateUserAsync method, then the window apperas, and after that nothing happens.
  I'm also not sure what the returnURL is supposed to be because all examples where either for an app version or just said return URL without giving any examples.</p>
