title: OAuth Card in MS Teams?
body: <p>I built my bot using Direct Line and authentication works there. But when I deployed my bot to MS Teams, pressing the sign in button does nothing at all. I used the following code:</p>
  
  <pre><code>AddDialog(new OAuthPrompt(
      nameof(OAuthPrompt),
      new OAuthPromptSettings
      {
          ConnectionName = ConnectionName,
          Text = " Welcome! Please Sign In.",
          Title = "Sign In",
          Timeout = 300000, // User has 5 minutes to login (1000 * 60 * 5),
      })
  );
  </code></pre>
  
  <p>I tried looking up documentation, but it seems they're using a different framework, or the v3 bot framework. How can I make OAuth work in web and ms teams?</p>
  
  <p>I'm using Bot Framework v4.</p>
