HTTP Error 500.30 - ANCM In-Process Start Failure in .Net Core

Dung Do Tien Nov 22 2020 554

I have a project written by Core 2.2 and now I want to migrate to version 3.0 but after migrating done and running the application I got an error HTTP Error 500.30 - ANCM In-Process Start Failure. 

 HTTP Error 500.30 - ANCM In-Process Start Failure

Common solutions to this issue:
- The application failed to start
- The application started but then stopped
- The application started but threw an exception during startup

Troubleshooting steps:
- Check the system event log for error messages
- Enable logging the application process stdout messages
- Attach a debugger to the application process and inspect

I deployed this project on IIS server 8

    You have to change Hosting mode to Out of process, It will resolve this issue for you.

    Project--> Right click -->Properties-->Debug-->Hosting Model

    Asp.Net Core 3.0 throw HTTP Error 500.30 - ANCM In-Process Start Failure

    I hope it works for you.
