Deploying ASP.NET Core App to Azure results in blank pages-CodePudding

I have a free tier Azure account. I have an ASP.NET Core MVC project, committed to GitHub, which I have developed in C# on Visual Studio for Mac build 8.10.23 (Community). Everything works perfectly when running locally. I wanted to deploy this to Azure, so it's publically available for testing.

I have set up continuous integration from my GitHub account to my Azure application. The build and deploy process both run and succeed whenever I commit.

Problem: When I access my application URL, I get only blank pages. It's as if the views will not render. I am able to access files in /wwwroot (by manually typing the website URL and something like /img/intro.png) and they display, so I know the web server is serving files. But it does not seem like ASP.NET Core is operating correctly, and I'm not able to see any errors in Kudu.

Any ideas are greatly appreciated.

The reason for this problem is that your middleware has no next method in pipline and is interrupted.

You need to change your Server.cs file like below.
