How to apply Serilog for asp.net core mvc

Question

Goal:
Use Serilog for asp.net core mvc and then retrieve log data in a txt file.

Problem:
The code doesn't work. What part of the code am I missing?

Info:
*Using .net 5
*Code from this page (https://github.com/serilog/serilog/wiki/Getting-Started) works in relation to console but not for asp.net core mvc

Thank you!
