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.
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

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.
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:
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"
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 :)...
after 6h endly
If for some reason you are unable to delete internal switches in Hyper-V UI:
go to regedit
HKLM\SYSTEM\CurrentControlSet\Services\vmsmp\Parameters\SwitchList
delete Windows Phone entry (or all)
reboot computer
start VS and run emulator which will set everything up
I had a similar problem and tried many solutions and got the emulator working by doing the below steps:
Remove all the virtual switches from "Virtual Switch manager"
Restart your system.
Goto Control Panel -> Network and Internet -> Network and Sharing Center -> Advanced sharing settings
Advance sharing screen
And enable "Turn on Network discovery" and "Turn on file and printer sharing" for all network profiles.
Start emulator.
Done.
The steps suggested by Magani Felix above worked for me, but I had to apply two additional steps:
After deleting virtual switches from devmgmt.msc, the remaining virtual switch entry can't be removed from hyper-v manager anymore (step 5). However, just leaving it there was ok.
The first time I started the emulator from Visual Studio it could not connect. When I looked at the virtual switch in hyper-v manager, it had been created as a private virtual network. Shutting down the emulator from both Visual Studio and hyper-v manager, and then changing the internal switch to internal virtual network solved the issue. Afterwards, the emulator would start from Visual Studio and connect.
Windows 10 pro.
After attempting all the above, and similar suggestions from other threads, what ultimately worked for me was to:
Uninstall Hyper-V: Add/Remove -> Turn Windows Features On / Off
Uninstall Visual Studio Emulator for Android
Reboot
In Device Manager, "Uninstall" all remaining "Hyper-V Virtual Ethernet Adapter" instances found under "Network Adapters" node
Reboot
Reinstall Hyper-V
Reboot
Reinstall Visual Studio Emulator for Android
Download a device profile and launch
profit
Not all the reboots may have been necessary, but I had been banging my head against this for too long.
I believe this was caused due to me adding and removing Hyper-V a few times in the past, and some VirtualBox conflicts (which I currently do not have installed, it hasn't played nice with Hyper-V for me in the past).
Thanks for all tips above, hope this helps someone.
The solution offered by Silmar worked for me. All-in-all it appears that at least for Windows 10 Pro that one should install Hyper-V but not configure any virtual switches as the emulator installer will configure things properly.
Try this OPTION
1.) Open Hyper-V
2.) Shutdown any existing configured Windows Phone emulators.
3.) Delete the existing Phone emulators you see in the list
3.) Click on “Virtual Switch Manager”
4.) Click on the “Windows Phone Emulator Internal Switch”
5.) Delete the existing “Windows Phone Emulator Internal Switch” by clicking “Remove”
6.) Click “Apply” and “OK”
This should work.
If this does not, then do this:
Now, open “Network Connections”
You will see there “vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch)”
But hey, you deleted this same switch in OPTION 1, but still it shows in the Network Connections page.
Now open Device Manager, Expand “Network Adapters”
You will see the names appearing under Network Adapter match the same as “Device Name” mentioned in “Network Connections” window
Find out the correct “Hyper-V Virtual Ethernet Adapter” to be removed.
Now, in Device Manager, right click the correct Network Adapter and choose “Uninstall”.
This should disappear from the list.
Open “Network Connections” and see that “vEthernet (Internal Ethernet Port Windows Phone Emulator Internal Switch)” will no longer be present there.
Open Visual Studio, run the project in your desired emulator.
This time everything will work fine and the Emulator will boot up Windows 10 or Windows 8.
I know it's an old thread but just thought I would chime in.
What fixed it for me was going into "Turn windows features on or off"... unselecting all the hyper v boxes... restarting my computer... then selecting all the hyper v boxes again in "turn windows features on or off" and restarting again....
This fixed it for me. I tried the solutions mentioned above but they did not work.
I have struggled for some days with this issue.
After I have read all forums and references, I have found the solution and fixed it. The solution was as following.
https://msdn.microsoft.com/en-us/library/windows/apps/jj681694(v=vs.105).aspx
Interference from other virtualization or networking software and drivers
Other virtualization and networking software and drivers can interfere with the virtual network used by the emulator to communicate with Visual Studio. The types of software that may cause a problem include:
-Virtualization software other than Hyper-V.
-VPN clients.
-Software firewalls.
-Antivirus applications that hook into the network stack.
-Network monitoring or logging tools.
-Other system monitoring software.
After I uninstalled some software to interfere, I can run the emulator successfully.
Hope this help.
Thanks
Open Hyper-V Manager.
Open Virtual Switch Manager on the right side like pictured below:
Remove all Virtual Switches that contain "Windows Phone Emulator Internal Switch" and "Microsoft Emulator NAT Switch" like pictured below:
On Visual Studio, Click on your emulator that you want to deploy your app on.
I received this message when running the emulator:
[Window Title] Windows Phone Emulator
[Content] Windows Phone Emulator is unable to create the internal
network switch:
Something happened while creating a switch: Failed while creating
virtual Ethernet switch.
Switch create failed, name = '186E24AD-DE28-4C32-A93D-FF494B43B772',
friendly name = 'Windows Phone Emulator Internal Switch': %%3758096900
(0xE0000204).
[Close]
Why it gives this error, and how could I fix it?
1.Go into Hyper V Manager.
2.Go into Virtual Switch Manager.
3.Create a new virtual switch called 'Windows Phone Emulator Internal Switch'.
4.Set it's connection type to Internal.
5.Now launch the emulator. It should work.
(May be a reboot will be needed)
I had the same problem after digging for couple of hours finally I did this:
Go to programs and features and turn of the hyper-v through "turn windows features on or off" then restart the computer and turn it on and restart the computer again to have a fresh hyper-v.
Run cmd where Xde.exe is installed (usually in "C:\Program Files (x86)\Microsoft XDE\10.0.10240.0") and run command "Xde.exe -v sdcard.vhd"
Run Xde.exe as administrator (you will get an error)
Run visual studio and try to open emulator by deploy a project.
I don't know witch one fixed the problem but the problem goes away.
I uninstalled Oracle Virtual Box and Windows Phone Emulator works fine now, thanks.
I build an easy App in visual studio 2013, creating it through the windows phone project. The main thing is that it's supposed to fetch data from a API of my choice and write to an XML- document. It worked code-wise but depending on what network I was using(Wireless), It gave me either and error or it worked. It worked if I compiled with my phone as the network supplier, but not on my wireless at home or the schools network.
The error I recived everytime was "the thread has exited with code 259"
I googled for some solutions, and I guessed (Not really sure it was the answer I was looking for) that the error was due because of the phone emulator "takes" my PC's IP adress or network.
They told me to just remove my phone emulator on Hyper-V manager and then just re-start my emulation and it should work.
After this was done, all hell broke lose, cause now, visual studio can't even connect to the emulator.It creates a new phone emulator in hyper-v, but can't connect to it. When I try to compile the app I created it says "Trying to connect to "WVGA 512MB" or if I choose another "WVGA 720". It does this for about 3-5 min and then it says "An error occured. Would you like to continue?"
Now I have no idea what to do. I've googled for almost 2 days and I am at lost. I've un-installed, re-installed, repaired all my visual studio but nothing helps. I am using visual studio premium 2013 if that helps..
I guess this is due to the network issues, as you said the emulator takes the default PC's IP address. But normally after removing the emulator from the Hyper-V Manager and when you try to restart it, it should work.
If none of them works try removing all the Virtual Switches from your Virtual Switch Manager which is within the Hyper-V Manager. Then create a new Internal type of a Virtual Switch and restart your machine. Then try launching the emulator.

(WP8) Emulator (XDE) Troubleshooting Tips
I'm getting the following error when attempting to run a Windows Phone 8 app in the Windows Phone 8 emulator (via Visual Studio 2012):
The Windows Phone Emulator wasn't able to ensure the virtual machine was running:
Something happened while starting a virtual machine: 'Emulator 720P.joel' could not initialize. (Virtual machine ID 7320013C-0597-4408A-9CCF-049166CE9926)
There's no other indication on what might be causing this problem. I have ensured the following:
I'm running Windows 8.1 Pro x64
I'm on a machine that supports SLAT (It's a Core i5)
There's no other virtualization software installed or running, other than Hyper-V
I've tried cleaning the existing switches from Hyper-V using XdeCleanup.exe, with no luck
I've tried uninstalling and re-installing both the Windows Phone 8 SDK and Hyper-V. Neither helped.
The Windows Event Log reports no errors with regards to Hyper-V or starting the emulator
I've tried reducing the processor count on the VM to 1 processor (from the default of 2). No effect.
At one point in the past (a few months ago), the emulator was working. It was around that time that I got a Windows Phone 8 device, so I started developing it. I've been wanting to test a few things out on the emulator rather than having to use my actual phone. The only thing that I can think of that changed since then, was that I upgraded from Windows 8 to Windows 8.1.
Does anyone here have any idea what might be happening, or know of anywhere else I can look for any hints on what might be the problem?
Well I can't say this will work for everyone but for me it was a matter of simply turning off windows firewall.
I had checked all other settings (BIOS, SLAT, etc) and even uninstalled/installed the Hyper-v feature but Hyper-V had been working fine. In fact I could open and run the emulator - just could connect from VS. Once I turned the firewall off everything worked.
You would think you could establish a range of ports to use but who knows what they would be?
I had the same issue and even now it, when I disable my wireless actually totally remove wireless lan and disable my bridged networks. Everything works fine. Please also make sure that internet sharing is not enabled on LAN.
that mean that you don't have insufficient RAM to be able to start your Emulator.
try to stop some running programs or services. and try again
I had the same problem and I solved it as follows:
First disable the LAN connection.
This can be done by going to
Control panel > Internet Properties > Connections > LAN Setting > Remove the tick mark(deselect auto-detect setting)
Press OK.
If any anti-virus is installed, then disable the firewall.
Then go to Hyper-V manager and delete all emulators present. Restart your emulator and it will work.

I thought I'd try some Windows Phone development. I had to upgrade to Windows 8.1 Enterprise to do it so it's a fresh install.
When running the Windows Phone emulator from Visual Studio I get the following
the emulator couldn't determine the host ip address, which is used to
communicate with the guest virtual machine
A few posts recommend removing the virtual switches and letting Visual Studio add them again as a fix.
When trying to remove switches from the Virtual Switch Manager in the Hyper-v manager I get the following

Another post mentioned having to add yourself to a Hypervisor Administrator group but I can't find such a group and I'm already in Administrators and Hyper-v Administrators groups.
I've been through the WP8 Emulator troubleshooting guide on MSDN. I've tried uninstalling Hyper-v and re-installing it which does remove the switches but puts me back in the same situation when I run the emulator again.
I've no idea what to try now and I'm going round in circles reading forum posts. Any help would be greatly appreciated.
Thanks
usually a virtual switch just for the windows phone emulator is created. If for some reason it isn't working I'd suggest re-installing the Windows Phone SDK.
