Do you see your "Virtual Switch" information under: Control Panel\Network and Internet\Network Connections? If not, you can try to recreate your "Windows Phone Emulator Internal Switch" again from Hyper-V to see if that resolves your issue. Try these steps below:

1.) Open Hyper-V

2.) Shutdown any existing configured Phone emulators.

3.) Click on "Virtual Switch Manager"

4.) Click on the "Windows Phone Emulator Internal Switch"

5.) Remember what the settings are displayed there (because you will delete it and recreate it)

6.) Delete the existing "Windows Phone Emulator Internal Switch" by clicking "Remove"

7.) Click "Apply" and "OK"

8.) Re-create the "Windows Phone Emulator Internal Switch" by clicking the "New virtual network switch" and use the same settings you remembered in Step 5.

9.) Then try to F5 from Visual Studio - which should configure a new emulator on the right virtual switch.

The solutions above did not work for me. I found out that the issue was with the Hyper v adapters so I decided to deleted them which caused hyper -v to create them again.

These are the steps

1. Run cmd as admin and enter the following commands

   set devmgr_show_nonpresent_devices=1

   start devmgmt.msc

2. This will startup the device manager and show the list of hyper v network adapters

3. Right click and uninstall all hyper v network adapters

4. Open Hyper v manager and delete the virtual machines

5. From Virtual Switch Manager (right side of hyper-v manager), delete all internal switches

6. Restart the system and run visual studio and launch emulator

I had similar problem, i tried the various solutions offered (cleaning up the Hyper-V images and network switches), reinstalling Hyper-V, reinstalling Visual Studio, restoring to Old System Restore point - but none of my actions didn't resolved the problem.

But i tried below action which fixed the problem, off course some might able to resolve the problem with above steps and other answers provided.

In my case, my virtual adapter doesn't have network connectivity. I shared my wi-fi adapter connectivity to virtual adapter. This fixed for me, i can able to deploy apps into emulator without any crashes.

For me, the following steps worked:

1. Open Hyper-V manager and delete all emulators

2. From Virtual Switch Manager (right side of hyper-v manager), delete all internal switches

3. From Control Panel->Network and Sharing Center, disable the virtual ethernet port for windows phone emulator

4. Start Visual Studio and start emulator from there (Just deploy a project)

   Update: Your old connection will stay disabled and a new connection will be created. If you want to delete the old connection, go to device manager, find the connection and choose "uninstall"

In my case there was a problem with my notebook modem. It is a Sierra Wireless EM7345 4G LTE. As soon as I deactived it the Win10 Mobile Emulator worked like a charm.

For me all above solutions didn't work. Maybe because my Ethernet is disabled.

My solution is similar to other:

1) delete vm's from hyper-v

2) delete all internal switches

3) create manually new switch and select wifi

4) install vm profile

5) start it :)...
