The Licensing conditions say: "three computers ... plus 3 virtual machines running MS VPC, Hyper-V or VMWare". Does anyone else use Oracle's Virtual Box to run VM's in a development environment? Whenever I install LinqPad on a VBox VM, it counts against my PC installs and is not detected as a VM. VM's are for tearing down and setting up quickly and so the "six transfers per year" doesn't cut it either. I actually bought a second license to have to stop deactivating from my non-VM hardware so often.
