title: Get thumbnail image of PDF using ASP.NET?
body: <p>I have a system where users can upload PDF documents. Rather than displaying the link to these PDFs as a title link, or a PDF icon link, I would like it to be a thumbnail of the first page of the PDF document.</p>
  
  <p>How can I get a thumbnail image of the first (or any specified) page of a PDF document, using ASP.NET 3.5?</p>
