I've been trying to get the emulator to work for days. Previously I tried the Windows Phone 8.1 Emulator as well as the Windows 8.1 Simulator and both were stuck at loading the OS.
Earlier today I installed the new Windows 10 Tools and thought I should give it another try with the new Windows 10 Emulator... And no, still the same result.
What's strange is that, the Hyper-V Manager seems to be doing OK. I can see the app displays correctly on the little Preview window (see the box on the left side of the picture below).
Also, breakpoints are hit, the project seems to be running OK.
As many answers have already suggested, I tried letting it running for an hour, but still nothing came up.
Things that I've also tried include uninstalling all the Virtual Machines as well as repairing the WP 8.1 Emulator, nothing has worked so far.
Please help, this has driven me completely insane. :(
Update
Not sure if this would help, but if I change the Windows Phone Emulator Internal Switch to use Private network instead of Internal, I will get a couple of warnings saying Unable to determine the Host IP address and then the Emulator will show up with the Emergency Call screen. Not much I can do from there as the three buttons on the bottom are not functioning at all.
I understand that changing the connection type is not the right way to do it, but this at least tells me that the Emulator can work, it's just a matter of how.
I believe you have two Windows Phone Internal Switch connections and one seems to be unplugged while the other is running. Disable the one that is unplugged and leave the latter. This worked for me after 2days of tinkering. God speed.
Try the following.
Open the Hyper-V Manager
In the Actions pane, click Hyper-V Settings
In the Server pane, select Physical GPUs
Uncheck, Use this GPU with RemoteFX
Click OK to save/close.
Attempt to start the Windows Phone emulator VM from within Hyper-V Manager or Visual Studio.
I solved this problem by simply adding XDE.EXE as an exception to my Windows Firewall.
Just today
Many times it is not stuck. It just does take too long to start. I have an 8 core processor and it took like 5 minutes to launch, I tought it was stuck but it did launch.

when you set it to private network, Windows can't interact with your WP Emulator. Open Network Adapter, and try disable and try start emulator again, then enable again this adapter if it is not work *
I contacted the Visual Studio Team a couple of weeks ago and looks like they have fixed this issue in the latest update. And here is how I finally got it all working.
Update your Windows 10 TP to the latest version (currently 10074).
Install the latest Visual Studio 2015 (currently RC).
Install Windows 10 developer tools preview from here (I got
some weird errors with Error code: -2147023294. Ignore them, go
straight to the next step).
Install the standalone Windows SDK for Windows 10 Insider
Preview from here.
Install the Pre-release Microsoft Emulator for Windows 10 Mobile
from here.
That's all! After all these are done, both my Simulator and Emulator are loading up fine.
In my case, deleting the internal switch from Hyper-V virtual switch manager helps, whenever you run your app using emulator as the target, it'll add a new internal switch by itself and the emulator will run normally (no longer stuck on loading screen)
The problem is, I have to do it every single time I restart my PC
The workaround steps to install the Windows SDK and Emulator are no longer needed.
We have released a fix as of 7PM PDT 30 April 2015 for the setup error
Windows 10 SDK 10.0.10069 : The installer failed.
User cancelled installation. Error code: -2147023294"
New setups should no longer encounter this issue.

This worked for me:
Go to Windows Defender.
Add exclusion following path: "C:\Users\UserName\AppData\Local\Microsoft\XDE\YourEmulatorVersion"
YourEmulatorVersion - for example 10.0.14393.9
2 days, tried all that is posted here but nothing worked! Finally, since it is a lot easier nowadays to (re)install windows without loosing your files (3 hours including updates), I just resorted to that. Same thing happened, but then I saw the alert that I had not yet activated my VS to run in developer mode :) Did that, and voila, the emulator now works.
If this might be helpful: my problem started when I installed Android Studio and disabled Hyper-V from Android. Enabling it back for VS just couldn't get me to run it again. But I hear there is a way to run both Android & VS emulators using VS emulator for Android. I will try to see how that works later...
I know the question is old, but none of the above answers worked for me so I write down my two cents:
Go to Hyper-V console and remove all emulators
Go to Devices Management, under network adapters tree node, delete all virtual switches
Run an emulator from Visual Studio and see the magic happen
I am facing problem in deploying windows phone 8 app in the emulator. But each time I am going to deploy its showing the message like the figure. Can any one please help me how can I get rid off this disgusting message? I am using using VS Express 2012 with update for in Windows 8.1 Pro.
You need to hit the Retry button. If that succeeds then log off of the machine and then logon again.
Pressing retry will add you to the Hyper-V administrator security group. After this you have to sign out of your development machine and then log in again for changes to take effect , and then deploy app to the Emulator.
My VS 2013 setup has been humming along fine for months now. Today I tried to update to Visual Studio 2013 Update 2 RC. Just like last time when I updated to Update 1, setup failed badly with a huge list of packages marked with the "Incorrect Hash Value" error. Unfortunately MS does not have an ISO yet for Update 2 so I can't take that route to complete the update like I did last time. Now I can't run apps on the Windows Phone emulator or on the phone (device) anymore.
I believe that the failed update caused my current deployment problems since the problem surfaced right afterwards. It could be due to some other NuGet package or Extension, but the update is the most likely cause due to the timing of events.
I did extensive reading on SO and tried all the noted solutions. None of them worked:
cleaned and rebuilt the test Windows Phone 8 project (multiple times)
restarted VS2013
rebooted
Exited VS 2013 and restarted it with the Emulator left open (for the Emulator test)
repaired the Windows Phone Emulator install
repaired the VS2013 install
Nothing works. After the IDE installs the app on to the emulator, I still an error dialog box saying:
"The application could not be launched for debugging. Ensure that the target device screen is unlocked and that the application is installed."
And in the VS2013 IDE status line I see the message: "Launching TaskHost.exe failed".
Does anyone know how to fix this? Note, I tried several WP8 projects that I know worked successfully before and none of them can deploy successfully anymore to either the Emulator or the Device.
I see this was asked a month ago, but I had this issue as well. If I left the Emulator running and tried launching it again, I would have TaskHost fail with a different error.
The following was what made it work for me.
Under the following:
Solution(Right-click) > Properties > Configuration Properties > Configuration
Ensure that your main project is set to 'Deploy.'
Have many reason to error.! So, If you doing with database such as SQLLite file or SQL compact file for your project WP, you should check it is used anywhere. Or choose Embed source copy in visual. That's my fail.And i fixed ok!
Did you try from the menus?
BUILD > Rebuild Solution
That worked for me just now.
I am encountering an error on my emulator.
I've been developing an application for windows phone, it used to run okay and there was no error.
Recently, i upgraded my visual studio, now my project cannot be loaded. So I tried reinstalling my visual studio.
After reinstalling, an Application Development Error occured. I've looked for a solution but have been unable to find one.
During my search, I found out that my emulator didn't work properly. It was starting up, but after 13 seconds it reboots again and starts up again, this loop keeps going for several minutes. After that my visual studio gives me an error.
This led me to believe that the error was caused by a virtual hard disk issue, so I choose the virtual hard disk from MicrosoftSDKs/Windows Phone/Emulation/Images/Flash.VHD and it is running now.
But after I configure my settings of the emulator to change its virtual hard disk to Flash.VHD, It doesn't work at all. It keeps restarting over and over again.
I have been trying to solve this error for 4 days.
I started working on windows-8 this morning and I am surprised that installed app not displayed in the emulator which I installed in the morning. To be clear.
1. I created the new project called Test1 using visual studio Express 2012.
2. I installed on the emulator.
3. I close the emulator completely.
4. After an hour I created Test2 using visual studio Express 2012.
But i am not able to find the Test1 project in windows-8 phone emulator.
But when i work on iPhone and android the apps will be available if i recreate the emulator.
What could be wrong?. Do I need to change any settings?
the emulator does not persist app installs to the base image. (this was true with WP7x emulators). I don't remember seeing anything that tells me it has changed.
Emulator shutdown + start == fresh new emulator. Only time it persists your app etc is when you change settings like display language etc and emulator initiates a restart.
