I have a Windows 8.1 Pro machine (not preview). In order to do Windows Phone 8 development, the emulators have to use the Hyper-V engine to run. When Hyper-V was installed it changed my network adapter settings for my ethernet card to utilizing the Hyper-V virtual switch, and disabled all the other items, such as IPv4, etc. It appears I can no longer set a static ip address on my box for my LAN, or at least it is not evident how to do it.
Articles that I have read suggest that I need two network adapters, but they seem to be geared towards a different type of infrastructure, which is different than what I am doing. I do not wish to purchase another network adapter. I simply want a static IP address on my box as my router is configured to route certain types of traffic to my box, and utilize Hyper-V just to run the Windows Phone emulators, but the emulators still have to access the internet.
