You could generate a temp HTML file to embed the desired PDF:
```
<body>

<object
  classid="clsid:ca8a9780-280d-11cf-a24d-444553540000" id="pdf1" 
  type="application/pdf"
  data="test.pdf"
  style="width: 100%; height: 100%">

<param name="src" "value"="test.pdf"></param>

</object>

</body>
```
What's interesting, to make it work with a local (file://) PDF document, I had to specify both data attribute and src param. When it was served via http from localhost, the data alone was just enough.

UPDATE: I could not tell why this doesn't work for the OP, so I've cooked up a very basic C# WebBrowser project demo'ing this. It works quite reliably in my environment (Win8, IE10, Acrobat Reader 11.0.3).

UPDATE: I think I understand why this is happening. Your project uses WPF, while my sample uses Winforms. Sorry, I did not notice this in the first place. WPF WebBrowser has a different security model, it runs in IE Protected Mode by default.

With WPF WebBrowser, I've managed to get rid of the prompt (note ), but I do confirm the Acrobat Reader control just hangs loading the file every now and then:
```


<body style="border: 0; margin: 0; padding: 0">

<object
  classid="clsid:ca8a9780-280d-11cf-a24d-444553540000" id="pdf1" 
  style="width: 100%; height: 100%; border: 0; margin: 0; padding: 0">

  <param name="src" "value"="test.pdf"></param>

</object>

<script>
window.onload = function()
{
  window.focus();
  pdf1.setActive(); 
}
</script>

</body>
```
Acrobat Reader control is known to have issues with Protected Mode. Rather than trying to find a workaround for this, it may be easier to host Acrobat Reader ActiveX control directly in your WPF project. Here's how it can be done:
