Thanks for contacting us.
Lazy Loading feature should not be used for trying to load core runtime assemblies.
Looks like we can improve our docs to clarify this and we will use this issue to track that work.

We've moved this issue to the Backlog milestone. This means that it is not going to be worked on for the coming release. We will reassess the backlog following the current release and consider this item at that time. To learn more about our issue management process and to have better expectation regarding different types of issues you can read our Triage Process.

I found the problem, when publishing webassembly it was clipped by default, but when loading on demand it was clipped after the clipping. The problem was caused by not being able to find the clipped assembly when loading on demand was used.

Thanks for contacting us.

We're moving this issue to the .NET 9 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.
