Question

After updating Windows 10 to build 10061 windows phone emulators (all 8.1 and 10) stopped starting. I get the following error: "Windows Phone Emulator is unable to connect to the Windows Phone operating system. Couldn`t setup the UDP port"

I tried "reparing" emulators, but nothing changed.

Hyper-V manager shows that virtual machine works, and it can be started directly from Hyper-V manager. As i said, in previous windows 10 TP builds it was OK.

Accepted Answer

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.

It works, thanks a lot! – nikita_97_10 Apr 28 ‘15 at 17:59 — nikita_97_10, Apr 28 ‘15 at 17:59

No need for steps 5 and 8. Once you try to run the enumlator from VS the virtual switch will be re-created. – stankovski Nov 30 ‘15 at 16:09 — stankovski, Nov 30 ‘15 at 16:09

Answer 2

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

Run cmd as admin and enter the following commands

set devmgr_show_nonpresent_devices=1

start devmgmt.msc
This will startup the device manager and show the list of hyper v network adapters
Right click and uninstall all hyper v network adapters
Open Hyper v manager and delete the virtual machines
From Virtual Switch Manager (right side of hyper-v manager), delete all internal switches
Restart the system and run visual studio and launch emulator

Thanks ! Since two days the emulator wouldn‘t work and I don‘t know why. Now it‘s fixed ! – TDK Aug 24 ‘15 at 8:41 — TDK, Aug 24 ‘15 at 8:41
seriously - if I could upvote this 1000 times - I tried everything else before this (couldnt launch visual studio android emulator) Thanks! – Adam Tuliper - MSFT Jan 27 at 6:44 — Adam Tuliper - MSFT, Jan 27 at 6:44
Worked like a charm. Thank you! – Luis Beltran Feb 5 at 9:08 — Luis Beltran, Feb 5 at 9:08

Answer 3

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.

Good call @mahender! this helps for me too! – dachibox Feb 15 at 19:12 — dachibox, Feb 15 at 19:12

Answer 4

For me, the following steps worked:

Open Hyper-V manager and delete all emulators
From Virtual Switch Manager (right side of hyper-v manager), delete all internal switches
From Control Panel->Network and Sharing Center, disable the virtual ethernet port for windows phone emulator
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"

Answer 5

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.

Answer 6

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 :)...
