`az webapp up` no longer works from dotnet publish directory

Question

I'm trying to deploy the contents of a dotnet project after running dotnet publish, but the newer versions of azure-cli complain with the following error message:

$ az webapp up --name MyAppService
Could not auto-detect the runtime stack of your app, see 'https://go.microsoft.com/fwlink/?linkid=2109470' for more information

Following the link, https://go.microsoft.com/fwlink/?linkid=2109470, I can see that it's looking for a *.csproj file, but that doesn't make sense to me, since I'm deploying files from my publish directory. From what I can see, if I run it from the directory that contains a *.csproj file it works, but tries to zip and upload all the source code and not just the published files.

It originally worked in azure-cli v2.0.66. Recently I downgraded to v2.0.75 (as indicated here https://stackoverflow.com/a/59529584) and it works also, but I would like to keep azure-cli up to date. I've also seen that the azure-cli has added an --html flag to deploy static files, but my situation is a bit different.

So the question is: How do I get az webapp up to work from the dotnet publish directory in versions of azure-cli >v2.0.75?

Answer 1

I think that there is some related bug.

I had a similar issue. Following this tutorial the final step was apply the az webapp up command but the deployed site only had a message saying "You do not have permission to view this directory or page". That means that no site was detected on the deployed site folder.

I applied the dotnet publish command and tried to run az webapp run from the published folder but the result was the same as you: "Could not auto-detect the runtime stack of your app, see 'https://go.microsoft.com/fwlink/?linkid=2109470' for more information."

Finally, from the root project folder I ran dotnet publish -o . and then az webapp up and got the deployment working as expected. This sounds really crazy because I finally got merged the published files with the source code.

This is my first attemp to use az webapp up, I hope that this issue to be solved soon.
