Well, the following is based on popular examples available on the web. What this does is "read" the pdf file and output it as a text in the rich text box control in the form. The PDFBox for .NET library can be downloaded from sourceforge.

You need to add reference to IKVM.GNU.Classpath & PDFBox-0.7.3. And also, FontBox-0.1.0-dev.dll and PDFBox-0.7.3.dll need to be added on the bin folder of your application. For some reason I can't recall (maybe it's from one of the tutorials), I also added to the bin IKVM.GNU.Classpath.dll. 

On the side note, just got my copy of "Head First C#" (on Keith's suggestion) from Amazon. The book is cool! It is really written for beginners. This edition covers VS2008 and the framework 3.5.

Here you go...
