Infer collection interfaces like IList come from the body in minimal actions

[halter73]

Currently, all interface parameters without an attribute are inferred to be services. I like this simplicity, but it might be more convenient for developers if we inferred collection interface types like IList and IEnumerable are from the body instead. This complicates the mental model a bit and it's not that uncommon to consume multiple services using IEnumerable, but it's worth considering. See #31658 (comment)

Thanks for contacting us.

We're moving this issue to the Next sprint planning milestone for future evaluation / consideration. We would like to keep this around to collect more feedback, which can help us with prioritizing this work. We will re-evaluate this issue, during our next planning meeting(s).
If we later determine, that the issue has no community involvement, or it's very rare and low-impact issue, we will close it - so that the team can focus on more important and high impact issues.
To learn more about what to expect next and how this issue will be handled you can read more about our triage process here.

Given discussion in #32516, we might want to avoid doing this for collections of simple types. Or maybe we exclude arrays? That would feel a bit weird though.

I think we should close this and wait for feedback.

Agreed!
