title: How do we implement in app purchase in windows phone 7
body: <p>Hi i am creating a windows phone 7.1 application, which requires in app purchases </p>
  
  <p>As WP7 does not have a specific in app purchase SDK like iphone does, can we use <code>paypal</code> for in app purchases, </p>
  
  <p>I am new to windows phone 7 and paypal API</p>
  
  <p>like open a mobile paypal site in <code>browsercontrol</code> when i click on payment button and get the payment done by the user and if the payment success return success message or if fail return failure message. </p>
  
  <p>i do not think <code>Movend</code> is a best option, as we have to maintain products database in their website also which i don't want.</p>
