title: how to post to facebook page wall from .NET
body: <p>I've created Facebook page.
  I have no application secret and no access token.</p>
  
  <p>I want to post to this page from my .NET desktop application.
  How can I do it? Can anyone help please, where can I get access token for this?</p>
  
  <p>Should I create a new Facebook Application? If yes, how can I grant permissions to this application to post on page's wall?</p>
  
  <p>UPD1:
  I have no website.
  I need to post company's news from .NET desktop application to company's Facebook page.
  All I have is Login/Password for Facebook Page Account.</p>
  
  <p>UPD2:

  How can I grant permissions to post to page's wall?</p>
