How can i remotely debug an asp.net core web app deployed on an azure app service

Question

I am working on an asp.net core web application.

I need to debug this application (put a breakpoint and inspect variables when this breakpoint is hit).

I can do this on my local computer, with visual studio.

I can do it too if i deploy my web application on a remote IIS Server.

But i want to do this when my application is deployed on an azure app service.

This container does not work with IIS. It seems an azure app service works with Kestrel (dotnet run command). And i don't know how i can remotely debug this application.

Thanks

Additionnal informations:

I am working with .Net6
What i mean by "container" is "Azure app service instance"
I am working with Visual Studio 2022 community edition
I am deploying with azure devops and azure pipelines

What is the .net core version ? Version of Visual Studio you are using ? — Harshitha Veeramalla, May 05 '22 at 13:10
What do you mean by "This container does not work with IIS"? Are you deploying a Docker container in App Service? — CSharpRocks, May 05 '22 at 13:11

@HarshithaVeeramalla-MT I can't attach to the process because this is a remote process... — Bob5421, May 05 '22 at 13:35
I think the answer here is, *with great difficulty*. The better solution would be to re-create whatever it is your trying to debug locally. — Liam, May 05 '22 at 13:35
I can’t re-create anything because this is an app service not a virtual machine. I need to debug through dotnet run process — Bob5421, May 05 '22 at 17:04
Have you tried [Attach Debugger](https://i.stack.imgur.com/3xeE7.png) — Harshitha Veeramalla, May 06 '22 at 06:14

If you want use remote debug feature, you need to use Debug model when you deploy your webapp.

Something like below in Visual Studio.

In azure devops, you can find it like:

Pipelines > Builds (or Pipelines), open your build pipeline
Click in Edit, Variables tab, change the value from variable BuildConfiguration from "release" to "debug"

It does not work because this is an app service on azure. Your method would work for a server with IIS for example – Bob5421 May 09 '22 at 10:46
@Bob5421 Ok，pls enable remote debug in your azure portal. It should be work，pls try it. – Jason Pan May 09 '22 at 10:47
