I am trying to follow the instructions on this webpage: https://devblogs.microsoft.com/visualstudio/hyper-v-android-emulator-support/
I have reached step 2 and downloaded the zip file. However, there is no executable. How do I install this preview? Is the preview the same as this: https://visualstudio.microsoft.com/xamarin/ ?

Update 2
My processor is: Intel (R) Core i7 950 # 3.07 GHz. I have the following BIOS: P6X58D-E version 0502
I initially enabled the two settings in the BIOS:
advanced/cpu configuration/Intel(R) Virtualisation Tesc
advanced/chipset/intel vt-d configuration/intel vt-d
Is there anything else I need to enable. I accessed my BIOS this morning to retrieve these settings (so I could update my question) and it appears the second one is disabled. I definitely enabled it (I even took a photo at the time and checked the photo today). I am going to try and enable it later. I want to research what it is first though because I tend to experience BSOD when I change BIOS settings.
On Windows:
To try out Xamarin Preview features, you need to install Visual Studio Preview version which can be install side by side of your stable/release Visual Studio.
On Mac: You can select preview update channel
Observation :
If I try to launch emulator by running the app, I get following error and deployment get cancelled.
But, If I launch emulator explicitly from Tools > Android > Android Device Manager > Start, then it launches and I can deploy and test on it.

I made that question to the Microsoft community months ago, the solution I came up with was to install the previous version of Visual Studio, 17.2.6, that could work with that phone. Then I got a new testing phone and I could debug on it just fine with any later Visual Studio version. But that old problem resurfaced when I tried to debug on my old phone again lately.
So, when I try to debug on the Samsung J5 I get the message that deployment is successful but debugging and the app stop. The app gets installed on the phone just fine, I can run it and test things, and for those parts that I would have added breakpoints I add temporary log entries to see what is happening. But debugging would be so much faster and easier. So I don't know what happened to Visual Studio 2022 after version 17.2.6 and the debugging on the J5 stopped working without changing the Android project's settings.
On to the output. The last lines of the Build output:

I have searched and searched and I can't find anything usefull. As for the configuration:
Android Options
Advanced Android Options
Deleting bin and obj after testing different Android options made no difference. The same options debug on the new phone just fine. And I haven't changed the developers setting in the J5. They are the same ones that VS 17.2.6 could debug with.
I am currently installing 17.2.6 to exist in parallel with 17.4.2 on my pc to see if that will help. But any insights regarding the reason behind my problem would be greately appreciated!
Edit: Community is not available for versions before 17.2.10 anymore. So I'll try 17.2.10.
Edit 2: 17.2.10 debugs on my old phone just fine. Same settings, same everything. So, since our target android version is now 13 on the solution on latest vs, I also created a clone of the repo to work with on the old phone because older vs can have only up to android 12.1 as a target version.
Yesterday I decided to try out VS2019 for Xamarin projects, so I created a Xamarin.Forms project and selected Master-Detail template.
Once it was created, I simply debug it (F5) and I see the test app in the Android emulator. Everything works fine.
Today, I try to run the app again, I have changed absolutely nothing in the code. I rebuild the solution and it builds successfully.
When I run the app, it fails for this reason:

The only solutions I have found deal with Android Studio, but I'm using Visual Studio 2019.
What can the issue be?
I tired xamarin native android and forms but both does seems to work. Both gives errors.
Tried creating blank xamarin android app without any code written in it, tired with xamarin forms app. Did a build, rebuild, clean, restarted system, restarted visual studio, running vs as admin all possible things but nothing worked out.

We have a ASP.NET project in the company that runs for 5/6 developers. All Visual Studio 2017 and debug on IIS Express, no crazy setting or anything to make it run.
1 colleague cannot get it to work, he always gets the following exception:
We had this problem a few months back, then out of frustration the PC was re-installed and the problem was gone. He didn't develop for a few weeks and today the problem appeared again.
I searched long and far but it's such a generic error I can't really figure this one out.
When I run the fusion log viewer I see the following result:

Are you trying to load a .NET 4 assembly with an EXE that asked for a diferrent CLR version? That requires an app.exe.config file that forces CLR 4 to be used.
Also please check the he has the same version of .NET installed.
1- Close Visual Studio
2- Delete all files from "C:\WINDOWS\Microsoft.NET\Framework......\Temporary ASP.NET"
3- Open VS
4- Rebuild then run
I have the same issue, its random. Just install missing package via Nuget for that project. Open Package Manager Console and type:
PM> Install-Package System.ServiceModel.Activities
and go on installing packages till there is no more error: then stop.
Turns out with the help of Fusion Log I found 1 file that was 0kb in size: C:\WINDOWS\Microsoft.Net\assembly\GAC_MSIL\System.ServiceModel.Activities\v4.0_4.0.0.0__31bf3856ad364e35\System.ServiceModel.Activities.dll
I restored the file from C:\Windows\Microsoft.NET\Framework64\v4.0.30319\System.ServiceModel.Activities.dll and it worked again!

I had a similar problem on my laptop. It turned out the Virtualization was turned off in my BIOS. My recommendation is to enter the BIOS setup on reboot (refer to manual as all machines are different) and see if Intel Virtualization is enabled. If not, you will need to enable it.
