Deploying ASP.NET Core MVC app to Azure Web App Service gives "Your web app is running and waiting for your content" - asp.net-core-mvc

Question

I am new to deploying web apps.
I recently finished working on a project I wanted to deploy to Azure. I used VS to publish it an Azure App Service with a GitHub CI/CD Workflow but when I try to access it I am getting the following page:
I have absolutely no clue why. Everything in the process went smoothly but the page is not showing. I could really use some help!
I searched around for this error but I couldn't find anything. I also tried different deployment strategies to no avail.
EDIT: turns out that my project files are not getting copied to the app service.
EDIT 2: I got the app running with a zip deploy but Id still like to use GitHub Actions to automate it

Answer 1

I don't know how you create the .yml file. I generate it by default, you can check below. It it will deploy failed and don't worry.
Then you will find the .yml file generated under your github repo. Please find it and copy the below script and paste there. Don't forget replace the app-name, publish-profile and so on.
Then it will auto deploy again, now it should be deployed successfully. If not, try to modify anything, and deploy again for testing. You can see I add Azure Web App-01 in the first line.
The script I have tested and it works well like below.
Then we will find the publish file under the wwwroot. The scm site is :
https://app_name.scm.azurewebsites.net/newui
Then we should add startup command in azure portal.
Then the application should works well in your side. 👍
It not works in my side, after investigating the reason,I found it missing the connectionstring and other configurations, so it not works in my side.
