How to publish Angular 9 Universal with .Net Core application in Azure App Service

Question

I have created an Asp.NET Core Web Application with Angular 9. I have added Angular Universal to my application. Now I need to publish my application into the Azure app service.

I have used the following command to build an application,

npm run build:ssr

After building angular universal application it will give two folder structures under the dist folder.

dist/{app-name}/browser
dist/{app-name}/server

For run the angular app separately using the following command,

npm run serve:ssr

It's working fine locally. Now I need to publish the application in the Azure app service. So far I have searched a lot of things and integrated them. But unfortunately, I did not find any solution to work for the last four days.

I need some more details about how to configure on .Net core side.

Can anyone help me to solve this issue? Any help is highly appreciated.

Edit:- I have followed the below answer the same thing
