This example depends on the PDFCanvas control that must maybe be
installed before the workspace PDFViewer can be compiled.

* In all my tests it was possible to compile the workspace PDFViewer
  without any further steps. The one and only thing that must be
  considered is that the Designer is not able to load the main form
  before the project was compiled one time. This is normal because the
  PDFCanvas control cannot be loaded before you have build it!

* However, If you are not able to compile the workspace PDFViewer
  directly then activate the workspace PDFCanvas and compile a Debug AND
  Release build. Now you should be able to compile the workspace
  PDFViewer.

  * If you get still compiler errors then add the PDFControl manually to
    the Toolbox:

	 * Open the Toolbox (Menu View/Toolbox), right click on an arbitrary
	   category and select "Choose Toolbox Items". Click on the Browse
	   button and select the file PDFViewer\bin\Release\CPDFCanvas.dll.
	   Click on Select, and in the parent dialog on OK. Now you can
	   compile the workspace PDFViewer.
