Audit.NET VS EfCoreinAction-SecondEdition

I’ve had great success using Audit.Net. It supports a variety of different data stores and I believe it logs things in a background thread…I could be wrong though. At any rate, I have been using it with the EF provider and a custom table. No issues thus far.

I've looked into this as well and kept seeing https://github.com/thepirat000/Audit.NET pop up. There's also this huge thing https://abp.io/ that has auditing as a component.

Sounds like you could use Audit.NET

Next, I started looking into different available options. I came across various libraries, compare them and finally I chose Audit.Net WebApi for the following reasons:

There are about a billion packages for accomplishing this, e.g. https://github.com/thepirat000/Audit.NET/tree/master/src/Audit.EntityFramework - for everyone reading this, please use tried-and-tested packages like that, instead of this yet-another-reinvention-of-the-wheel.

Got this approach to making a dropdown from Jon P Smit's app https://github.com/JonPSmith/EfCoreinAction-SecondEdition

I want to write a filter like here /BookServices/QueryObjects/BookListDtoFilter.cs (Query Object pattern) but applying to my situation. I have a Course table, which is linked to tables Module and Instructors as Course-Instructors like Many to one and Course to Modules like One- to- Many. One Module might have many videos (one -to - many). I need to filter courses by Instructor and by the Duration. How would i achieve that? I think that at first I probably need to alter CourseDTO class to include fields of interest there (Duration and Instructor's name) to be able to fill in them through linq queries in subsequent stages?
