PDFLib dll not working in .net4.0
<p>I was converted my .net2.0 project into .net4.0.</p>

<p>Now I could use pdflib.dll.
I recieved the below error.</p>

<blockquote>
  <p>"Declaration referenced in a method implementation cannot be a final method.  Type: 'PDFLibNet.xPDFBinaryReader'.  Assembly: 'PDFLibNet, Version=1.0.6.6, Culture=neutral, PublicKeyToken=26d87f7d66fb2aee'."</p>
</blockquote>

<p>In .net2.0 and net3.5 it hasworked for me but not in .net4.0.</p>

<p>How can I handle this?</p>

<p>I need any suggestions.</p>
