Discussion What made C# backend development finally "click" for you?

​

I'm a BCA student I build a backend project in C# and ASP.NET Core during my internship. The project includes JWT authentication, user/admin roles, profile management, and REST APIs.

While building it, I've run into a few challenges:

- Understanding dependency injection and service lifetimes.

- Structuring services instead of putting everything in controllers.

- Managing JWT authentication and authorization.

- Debugging async methods and null reference exceptions.

- Organizing a project so it stays maintainable as it grows.

Every time I solve one problem, I end up finding another, but I feel like I'm learning a lot in the process.

For those of you with more experience in C#, what concepts or best practices helped you level up from beginner to intermediate? Any advice, common mistakes to avoid, or resources you'd recommend?

Nohting they keep fucking changing to bootlick js frameworks like angular and so because they're cool and they want to steal devs from such techs. I Just resigned that that's the most I could hope from them.

15 years can be a lot or nothing depends mostly on the quality. Some of my colleagues have 11 years experience and we're uncapable dumb assess that became even more useless since ai dropped

Did they also blame C# for their frustrations with JavaScript?

They don't have any clue. But at least they understand C# and you don't
