I have a newly created ABP Commercial tiered application. I am deploying the project to Azure using a CI/CD pipeline, and the pipeline works perfectly. However, when I run the app, I encounter the following error: “HTTP Error 500.30 – ASP.NET Core app failed to start.”

1. I deployed the same project on IIS, and it is working fine.

2. To investigate the target framework issue, I created a new .NET 8 project and published it on Azure using Visual Studio, and it works.

3. I also tried the following solution, but it did not work for me:

   1. Configuration issue:

      i) Changed hostingModel from “inprocess” to “outofprocess” in the web.config file.

      InProcess

Out Of Process

ii) Updated the Azure app service configuration: Platform settings -> Platform -> Changed from 32-bit to 64-bit.

2. Published the same project on Azure using Visual Studio, but I am still encountering the same error (“HTTP Error 500.30 – ASP.NET Core app failed to start”).

Here it’s publish profile:

4. I also checked the error logs in the Application event log on the Azure App Service and the eventlog.xml file in the Kudu console, where I found the following errors.
