title: .NET open PDF in winform without external dependencies
body: <p>Is there a FREE library which will allow me to open a pdf and show it on a winform project. I know I could open it in adobe reader or something but it always seems so bloated to me and I would be relying on it being installed. Is there a nice lightweight alternative where I could just include a dll in my project or similar avoiding external dependencies. </p>
  
  <p>I don't need much functionality just view, change page zoom..</p>
  
  <p>I have seen a few libraries but they seem to be about creating PDF's not viewing.</p>
