Today I fired up Visual Studio to create a Windows Phone application, just like I had done the past couple of days, only to be faced with;

[Window Title]
Windows Phone Emulator

The Windows Phone Emulator wasn’t able to connect to the Windows Phone operating system:

The emulator couldn’t determine the host IP address, which is used to communicate with the guest virtual machine.

Some functionality may be disabled.

Hmm, what the **? I had a look around the internet and saw some horrible posts about re-installing the SDK. Ergh. One post mentioned an internal developer who had to uninstall VPNs, and remove all the virtual switches. None of which filled me with joy. So I opened Hyper-V manager and looked at the virtual switch settings for the phone emulator. I nodded sagely, then removed it – hoping the emulator would spot it was missing the settings and recreate them. It worked, the emulator recreated the settings and worked. Hurray! Hopefully it won’t happen too often…strange.
