I've installed Visual Studio 2013 Premium and the WDK 8.1 Update, unfortunately though, when I open the Printer Extension Sample ([https://code.msdn.microsoft.com/windowshardware/Printer-extension-sample-0e3e1562][1]) from the WDK samples pack, the reference to PrinterExtensionLib is broken.
I'm sure there must be a prerequisite I'm missing somewhere, but I've got the latest .Net, latest updates to Visual Studio and the latest WDK 8.1, so I'm not sure what I'm missing.
I've placed the sample project in c:\apps as the sample tells you to do, but still not joy.
Does any body know what I'm missing / haven't installed?
Well, I've just spun up a Windows 8 VM and the reference seems to be satisfied, so I guess you can only build some of these samples on a Windows 8 Machine. The sample states that it should be run on Windows 8, but I didn't see build machine requirements.
So, I guess the answer is, I was missing Windows 8 (Yuk).
