[nzig]

Previously, using parameterless Depends() in a generic context would bind the dependency to the first encountered concrete type.

Fixes #9450.

Looking forward to this fix. I want to use code from #9450 as example to implement injection of contollers in my project

Hi @nzig, I've been watching this pr all month. And I'm already beginning to think that if it will be put in, it will not happen very soon. But it's a very cool fix, which will allow to write less monotonous code for your classes. Maybe it's possible to do something to get this pr accepted faster?

@9en9i That's up to @tiangolo. He's the only one that can merge PRs.

@tiangolo hi, is it possible that this bug fix request will ever be accepted?

[9en9i]

@Kludex @JarroVGIT @jgould22 @ycd Perhaps one of you can somehow contribute to the promotion of this pull request? This request fixes a feature that was added a little less than a year ago, and it would be nice to get full functionality.

@tiangolo hi! This is a very cool feature that makes the code more readable and clean. Should we hope for its will be accepted?

This will be available in the next hours in FastAPI 0.110.1 🎉
