Problem encountered on https://dotnet.microsoft.com/learn/xamarin/hello-world-tutorial/devicesetup

Operating System: Windows 10 Pro

Using the Hello World xamarin example in Visual Studio - I'm unable to start the Android Emulator.

When I click on the Run button in the Android Device Manager - the error appears immediately (See attached)

Error-AndroidDeviceManager (Emulator including Google Play/Google API) enter image description here

Emulator error

Device error: WARNING: unexpected '-prop' value ('monodroid.avdname=pixel_2_pie_9_0_-_api_28'), only 'qemu.' properties are supported WARNING: unexpected '-prop' value ('emu.uuid=4b63b139-cc77-4b66-9200-0d25f8fc545e'), only 'qemu.' properties are supported

Same Error when Emulator is not using Google Play/Google API

Visual Studio 2019 enter image description here

Windows Features On/Off (see attached - shows Hyper V / Virtualization enabled as per documentation): WindowsFeatures enter image description here

I tried this way too - adding the Virtual Machine Platform - same error enter image description here

Android SDK Settings

Android SDK - Platform

Android SDK - Tools - part 1

Android SDK - Tools - part 2

Android SDK - Tools - part 3

Android SDK Version: enter image description here

Could the issue be related to the Android SDK Tools - only showing Android SDK Command-line Tools versions 1.0 to 2.1? Could the issue be related to Android Repository perhaps missing on the bottom right hand side? enter image description here

I've now also included the Android SDK Repository under the tools - but this is still not coming through: enter image description here

You should also check Virtual Machine Platform in Turn Windows features on or off. Also, note that the tutorial that you linked to use an Android device for USB debugging.

EDIT Here are my Android SDK Manager settings
Platform Settings

Platforms tab
