Crystal Reports in WPF, which references do I need to add to my project?

In this software development game it can be hard to avoid developing reports, I haven’t had the need to use CrystalReports in many along year, but last year I had the misfortune of using Microsoft’s shoddy reporting services for a client and decided after that that I would try at all to avoid a repeat of the experience!

So here I am with SAP’s shiny Crystal Reports, so far so good, except for some slightly worrying bitness problems, I am developing on Windows 7 64bit targeting x86 and found that I _sometimes_ had to set my project’s build target to x86 (from AnyCPU) to avoid getting exceptions thrown like this:

The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception

With an inner exception like this:

   failed due to the following error: 80040154 Class not registered...
