Xamarin - Error on creating emulator not working - windows

I downloaded Xamarin to start learning some app development. When I go to create a android emulator, it finishes downloading but I keep getting this error when it reaches 100% on the download:
Device could not be created. Please file an issue by choosing "Report a Problem" in the Help menu, and attach your logs.
Error summary: avdmanager has returned non-zero exit code: -2147467259. Please check logs for more information.
I've attached a screenshot as well. I tried searching for any similar errors but no luck. Any recommendations would be appreciated.
Using:
VisualStudio 2019, Win 10 Student, Hyper-V enabled, Intel i7 8th gen w/ 16gb ram

Visual Studio 2017 Graphics Debugger - No such interface supported

So i have a new set up of windows 10 Home Edition on my PC and installed VS 2017 Community Edition. When i build and run the app it runes absolutely fine. But if i use the graphics debugger i get the app open and i print screen to snapshot a frame. The window opens and it shows the following
If i choose to open that frame then i get the following error - An error occurred. Playback of your application may be incomplete(HRESULT = 0x80004002) "No such interface supported"
Does anyone have any ideas what this could be as it worked fine on my laptop and for the record. Opening a brand new Directx12 app project with the spinning cube also does this.
Please have a look for the question at here. I suppose you are using Windows version 1809 or higher.
Graphics Debugging Tool does no longer support DirectX12 after 1809. Instead, you should use the PIX for Windows in future.

Deploying to Windows Phone 10 fails on Visual Studio

So many things happened that I don't know where to start. Seriously, shouldn't this be simpler?
Edit: Someone here knows how can I contact Microsoft to tell this? Or even, can someone tell them about this problem?
I have the last Windows 10 desktop and also have Windows Phone 10.0.10512.1000. I installed Visual Studio 2015 with tools for Universal Apps development (and also 8.1). I have a Lumia 730.
So I connected my phone with my USB cable. Everything fine, the phone gets recognized and I can navigate through the folders.
Then I started Visual Studio 2015 and created a blank universal app. Compiled and tried to deploy. Now this is happening to me: Visual Studio hangs for some moments. Eventually I get an error telling that the device was not found (DEP6200).
I already tried dozens of solutions:
disconnecting from wifi in my laptop and my phone
restarting the IpOverUsbSvc service
rebooting the computer and the phone
deleting the devices in the Device Manager
Registering and Unregistering the phone (it sometimes works)
All of the above with the phone screen unlocked
disabling Hyper-V
disabling firewall
Other solutions that failed miserably
I also tried to use that Windows Phone Developer Power Tools. When I try to use it, it asks me to install some "Phone Tools Update Pack", but when I try, it says that the operation didn't succeed, and also shows the NRE message string (object reference not set to an instance of an object).
I can go through the phone's folders without any problem. I tried to reinstall the drivers... i tried everything.
It's quite sad.
Do you guys can think of some more thing to check?
EDIT: I tested this app before doing all this: https://blogs.windows.com/buildingapps/2015/07/09/just-released-windows-10-application-deployment-tool/
And it worked. If that's the case, is Windows Phone 10 deployment over Visual Studio working already or we have to wait some more time?
Edit2: After making some changes to my app manifest and choosing "ARM" config, now I get this:
1>Deploying to SD Card...
1>Updating the layout...
1>Copying files: Total <1 mb to layout...
1>Checking whether required frameworks are installed...
1>Framework: Microsoft.NET.CoreRuntime.1.0/ARM, app package version 1.0.23117.0 is not currently installed.
1>Framework: Microsoft.VCLibs.140.00.Debug/ARM, app package version 14.0.23019.0 is not currently installed.
1>Installing missing frameworks...
But it just stays there. It's stuck, and it stays there forever. At least I got some info... Its more or less the same steps that WinAppDeployCmd does, but the command line app does it successfully.
Somehow the problem got solved. I created a brand new project and did this:
1 - In your phone, try disabling the developer mode on your phone. What an unexpected development!
2 - Disable the "phone discovery" thingy. I don't know the name of this configuration in english (as my phone is in Portuguese). Just in case.
3 - Choose the correct architecture. This is obvious, right? In my case, ARM. If you try deploying with x86 or x64, it should give you an error. For me, it didn't.
From now on, you should be able to deploy your apps in both developer mode and non-developer mode. It just works, somehow. And it might NOT work for you, sorry. I think I got lucky.
It worked even after a reboot. So the solution is "pretty solid" (in an universe where gelatine is pretty solid).
I had the same problem. I tried the fix of the comment and went to devices manager.
Under USB-Devices there were three Lumia 920s listed.
I selected the second one and clicked on uninstall.
At the end it asked me to restart the Computer. I clicked on NO.
(When I uninstalled the first or third one, it didn't ask me that).
Then the error disappeared (now another common one appears (HRESULT: 0x80073CF6))
I have a Lumia 950 xl, with windows 10 installed, anniversary version. I had the same problem, and my solution was to turn on 'Device discovery' and 'Device Portal', and also keep the 'Developer mode' on.
I believe the only necessary option was the 'Device discovery' though!
Just in case someone still runs into this issue, I had something very similar with my Visual Studio 2015 professional update 1 but I couldn't even deploy to an emulator.
The issue has gone after I upgraded to Visual Studio 2013 update 3.
I had the same issues on Windows 10 with Visual Studio 2015. I updated the the UWP SDK to Anniversary Edition Build 14393, set the target framework to this and it worked. I guess the incompatibility between the device version and sdk version was not allowing the device to be discovered by Visual Studio.

I am not able to find windows phone emulators in VS 2015 Latest community version

I'm not able to see any of emulator in VS 2015 for windows phone. My system has all requirements to run an emulator. previously I was able to debug on emulator. After uninstalling and reinstalling VS2013 to VS 2015 (latest)I'm unable to get emulator list and i'm getting error
"There were deployment error" and error list shows " Error 1
Exception from HRESULT: 0x89721500".
Please help me to solve this problem as I'm unable to test my window phone apps on my system.
right click your project, and see if there's a menu item "Add Windows 8.1". That worked for me, even though it was a Windows Phone 8.1 project. Huh!

Windows Phone invalid license in my app?

When I run my app in the emulator (either Debug or Release build) I get the following error:
"App Name" license is invalid. Please purchase the product.
And gives me the "uninstall" or "buy" options.
Notes:
This app ran on the emulator fine until recent VS update.
I tried
cleaning the project and didn't help.
This is using Windows Phone 7.1 emulator.
This is the only relevant information I've found so far but their error was happening on the device, not the emulator.
Any help is greatly appreciated.
Try running "C:\Program Files (x86)\Microsoft XDE\8.0\XdeCleanup.exe". This will recreate the emulator for you and should clean out any bad state.
If this continues to happen on any app (including, say, HelloWorld), then can you please share out a xap?

System gets stuck while running windows phone emulator

I am developing an application for Windows Phone in Visual studio 2010 ultimate using wp7.1 SDK in Windows 7 32 bit and 3GB RAM. My system often gets stuck and then restarts sometimes when I run the application on wp7 Emulator (2 or 3 times an hour). Before restart it displays the message: "Display driver stopped responding and recovered" and leads to a blue screen displaying "some lines with Contact system admin".
I am not sure why, will need more details. Try installing the 7.1.1 update for the SDK, it is meant for low profile devices, but I am just hoping this will resolve your issues too.

Had the same problem. Just start your sdk installer. There will be a option of repair of deleat. I repaired my sdk first but it still did not work. I then deleted my sdk and reinstalled it. Worked like a charm.
But you must you know that I was not able to delete my sdk too. My antivirus was doing something wrong and stopping the uninstall of my sdk. So I had to delete my antivirus... than my sdk. Than reinstall the sdk, reinstall the antivirus.
It all worked great after.
