Remote debug Azure web job with .NET 6 in Visual Studio 2022 - azure

I followed this tutorial to create a simple web job in Azure: https://learn.microsoft.com/en-us/azure/app-service/webjobs-sdk-get-started. The web job itself does its job, consumes the message in the queue and I see them appear in Application Insights.
However, I want to debug the function on my local machine by using the tools available in Visual Studio 2022.
I have published with following profile settings:
Next I've attached the debugger under het Hosting menu:
First thing I noticed is a message about no symbols being loaded when putting a breakpoint in the function:
When I add a message to my queue, it gets consumed by the web job but the breakpoint is never hit. I've been reading a lot of similar questions regarding a this issue but I'm not progressing any further.
In Azure Portal, I've enabled Remote debugging under Configuration > general settings
In Visual Studio 2022, I checked if the correct process is attached
Here I'm a bit confused thou, the connection target is connecting through port 4024, which is according to this document, the port for Visual Studio 2019. However, a connection target with port 4026 is not found.
What am I missing here? Am I forgetting another setting somewhere?
If have tried changing the stack setting .NET version from APS.NET V4.8 to NET 6 (LTS) but that didn't help.
Should the platform architecture match the architecture of my machine in order to get it to work? Or is this not linked in any way with the debugger?
Is there anything else that I should check or try? Because my hair is turning grey here :)

Apologies for the delay here!
It should be 4024 for both 32 and 64 bit.
See this Azure doc: Remote Debugger Ports on Microsoft Azure App Service
Typically, the error “The breakpoint will not currently be hit. No symbols have been loaded for this document.” -- This error message indicates we can start debug process and attach, but cannot set a breakpoint on any or some lines of code in the project.
Most, likely cause: Application is built without debug symbols or debug symbols are not available
Kindly try these steps:
Verify Debug Symbols are being used and published and in sync
Workaround the issue by disabling “Enable Just My Code” from the
Tools >> Options >> Debugging >> general menu in Visual Studio
Other things to narrow-down the issue:
Debug symbols must be available locally or deployed to the Azure App Service, and must match the local code you are trying to debug.
It is recommended to use Cloud Explorer over Server Explorer to
connect and debug which requires the Azure SDK.
You could optionally Manually Attach a Debugger to Azure Web Apps to troubleshoot this further or recommend this as a workaround.
(old blog, try similar steps)
Kindly verify the port (Visual Studio remote debugger port assignments ) required is open in the corporate firewall and on your local machine.
As a test, you may use tool like Wireshark/netmon, to see if the port successfully connects to the port (4024) needed by the process.

Remote Debugging Blazor WASM on Azure?

I've tried using the standard Blazor template app to remote debug on an Azure app service and I get the following error:(the app run fine if a compile to release, though not debugging of course.)
I compile to debug any CPU.
UPDATE
I can debugger in my .razor pages.
PRIVIOUS
Judging from your error message, the problem may be caused by unsuccessful release of some files and other factors when the program was released.
In order to solve your problem, you can tell us the version of Visual Studio you are using and how you created the project. This problem is mostly related to your development tool environment configuration.
Here is a suggestion, test it by yourself and it runs normally.
Visual Studio 2019 Enterprise Edition (other versions should also be normal)
Configuration before project release
Start remote debugging
The final result

visual studio 2017 remote debugging azure api app: "The breakpoint will not currently be hit. No symbols have been loaded for this document."

I'm trying to remote debug an asp.net core 1.1 api app (targeting .net framework 4.5.2) that's running on Azure.
I attach the debugger via Server Explorer. The debugger attaches to the correct process. But any breakpoint I set has the message "The breakpoint will not currently be hit. No symbols have been loaded for this document."
All answers I've seen to such a problem assume that the modules window shows all modules loaded by my project, but in my case the modules window is empty!
I'm on VS2017 15.4.
If I remember correctly, I was previously able to remote debug the same project with version 15.2. The problem started occurring when I updated to 15.3 but I didn't pursue it at the time.
I submitted the problem on the MS forums: Can't remote debug Azure API app
and now I have received an official reply that it is indeed a bug in VS, and a fix will be available in the pending release (15.6).
They also suggested a workaround, which I tried and indeed worked: Manually Attach a Debugger to Azure Web Apps
Which involves:
Going to the web app Application settings in the Azure portal, and making sure that Remote debugging is enabled,
In the VS menu: Debug > Attach to Process..., entering the web app url with the debugging port, e.g.:
myapp.azurewebsites.net:4022
Then in the credentials that appears, entering the username & password that are available in the app's Publish Profile, which can be downloaded from the portal. If the username is $myapp, it should be entered like this:
$myappp\$myapp
Then choosing Managed(v4.6, v4.5, v4.0) code and then the name of the Core app.
Actually, I had found and unsuccessfully tried similar approaches before. The key for me was step 3. The others had suggested entering the username as .\$myapp, or myapp\$myapp. So make sure to enter it as written above.
BTW, seeing that the above blog post is from almost 2 years ago (Feb 2016), whereas the problem I'm experiencing was introduced only a few months ago, it seems to be a cure-all, and it is therefore worthwhile, for anyone who has to deal with remote debugging Azure apps, to save this information for future reference.
UPDATE:
After updating VS 2017 to version 15.5.2 the problem seems to have been fixed.
I have had the same issue with Visual Studio 2019. The fix for me was just to go in the VS menu: Debug > Attach to Process, and try to connect as describe by #Dan Z. The connection was not established, saying No connections found, but attaching a debugger from Cloud Explorer again, right after an attempt in "Debug > Attach to Process" is always successful. That is most probably a bug in VS

Unable to remote debug asp.net mvc core application on IIS8 (AWS EC2)

I have an MVC core website written in C# which is deployed to an AWS EC2 Instance with Windows Server 2012 R2 and IIS8 deployed on it.
I am trying to remote debug the application as I am getting errors thrown which I don't when running locally (details for another post maybe).
On AWS Console, I have a security group with the following Rules as guided by here:
and when I click on Debug->Attach to process, and browse to my AWS instance, I can see the correct dnx.exe process, however, when I attach to that process,
I get the The breakpoint will not currently be hit. No symbols have been loaded for this document
I've tried going to Tools->Options->Debugging->Symbols and clicking Load all symbols as it is my understanding that since VS2012 the symbols do not need to be deployed, but rather just on the local machine doing the debugging, taken from here.
In versions of Visual Studio before VS 2012, debugging managed code on a remote device required that the symbol files were also located on the remote machine. This is no longer the case. All symbol files must be located on the local machine or in a location specified in the Debugging / Symbols page of the Visual Studio Options dialog box. See .NET Remote Symbol Loading Changes in Visual Studio 2012 and 2013 on the Microsoft Application Lifecycle blog.
I can see the connections being initiated in the MSVSMON process on the EC2 instance.
I feel like I'm close but I'm just missing one simple thing.
You need to check on which port the Remote Debugger is running and allow inbound traffic on that port by opening Inbound Port [4024 in my case] with a Custom TCP Rule for Remote Debugging.
You can check the port used by Remote Debugger at Tools > Options in the Remote Debugger Menu.

Azure Service Debugging hangs on attach to process how can I trouble shoot this?

I'm trying to debug a deployed Azure Worker Role. I have the service published from visual studio and confirmed it is running on my Azure dashboard. In visual studio I right click the Instance of the role (only 1 is there) and select debug. After 5+ minutes I get the process dialog box and I select the WaWorkerHost.exe process. After that nothing is happening - I have a visual studio dialog that says "A remote operation is taking longer than expected". It has been 25 minutes so far.
1) I need to be able to debug my service and I'd like to do it vs the Azure published version. How can I debug this hanging operation?
2) 30+ minutes is not reasonable to wait for a debugger to attach. Is there any way to improve the process?
To be able to debug your Azure cloud service, you first need to make sure it is built with the Debug configuration and that the remote debugger feature is enabled, then you'll be able to attach to the role from Visual Studio as if you were running it locally.
You can follow these steps to enable the debugger and attach to the service: https://azure.microsoft.com/en-us/documentation/articles/vs-azure-tools-debug-cloud-services-virtual-machines/

Debugging Azure: Error attaching the debugger to the IIS worker process

I have a web application asp.net to deploy to Windows Azure. I try to run it on local first. But when debugging, I catch this error from VS2010:
"There was an error attaching the debugger to the IIS worker process
for URL 'http://127.255.0.0:82/' for role instance
'deployment16(6).WindowsAzureProject2.WebApplication3_IN_0'.
Unable to start debugging on the web server ......."
I've search so hard to find the solution for this problem but there's nothing seems work for me. I'm a newbie in Windows Azure, it's really a big trouble with me.
I had similar problem with Windows 8, debuging a cloud application with Visual Studio 2012 RTM and Azure SDK 1.71, when trying to launch the application into the compute emulator. It was a very simple app, but I used Azure diagnostics. At the end these are two things I have changed that have work for me, both turning on Windows 8 features (so go to Win8 and open 'Turn Windows Features On/Off'.
Activate the checkboxes for:
Internet Information Services Hostable Web Core
Internet Information Services > World Wide Web Services > Application Development Features > ASP.NET 4.5
Internet Information Services > World Wide Web Services > Health and Diagnostics > Tracing
Internet Information Services > Web Management Tools > IIS Management Scripts and Tools
That worked for me, it makes sense, as I'm using Visual Studio 2012 and trying to get some trace information using diagnostics in Azure.
I hope this will work for you or give some tip about the problem. In the case of being useful information, remember to vote as response or as value tip.
Thanks,
Mike
This usually happens when there's a problem with the project to be deployed to the emulator (WindowsAzureProject2 in your case).
Try the following:
Check %UserProfile%\AppData\Local\dftmp\IISConfiguratorLogs\IISConfigurator.log file for the error messages. See more details in this answer.
Make sure your project can be started without the emulator. It's a web project, so just try to start it as a regular web project. Or publish it to the separate folder and try to create a website in IIS of it.
Check your *.csdef and *.cscfg files to make sure all the configuration is correct.
Make sure that the build output of your project is not empty. You can do this by going to IIS, find the site with the name similar to deployment16(6).WindowsAzureProject2.WebApplication3_IN_0, right click --> Explore.... Make sure that this folder is not empty and contains all the files required to start a web project successfully.
BTW, there's a similar question: Debugger can't connect when starting local azure project
Follow step 11 from http://www.microsoft.com/en-us/download/details.aspx?id=35448. Worked for me on Windows 8 with Oct 2012 SDk
I just have today the same problem trying to Debug locally with Azure Storage Emulator in Windows 7. So in the Azure project properties, in Web tab, I checked the radio button 'Use IIS Express' and it debugged without problem. I hope this helps someone.
I encountered this exact same problem when I upgraded an existing Azure solution to the Azure SDK 2.1. After some hunting around I uncovered that the upgrade had automatically set the "Local Development Server" setting to "Use IIS Web Server".
Changing the "Local Development Server" setting to "Use IIS Express" fixed the problem immediately.
To access this setting right-click the Azure cloud project file in your solution, select the "Properties" option, tab down to "Web" and you'll see the following setup.
Also, make sure you run Visual Studio as administrator
Please check the version of emulator you have installed. If your code is created in older sdk and you have a new emulator installed it will give you this error.
Check the version of Azure APIs in your project, go to Project > references and right click on Azure dlls to check the version, same sdk version must be installed on the system, higher are optional as azure 2.x are not backward compatible.
