Convert PDF to TIFF - Examples dont work?

Does someone have an example of aspose PDF to TIF (TIFF) conversion that works.

What reference do I need to add, I cannot get most of the code samples to compile.
I am trying to change the C# example to VB but they dont seem to be workable.
Any VB.Net Solutions?
