NuGet icons are missing for most Microsoft.Extensions.* packages for the latest 3.1.0 versions.

3.0.1 version had icon

3.1.0 is missing an icon
The problem might be that the icon is in the nupkg package twice, this will be fixed in a 3.1.1 release as I understand. I'll find the issue and link it.
Here we go: https://github.com/aspnet/Extensions/issues/2744
Yes, it's related to that issue. We were switching from IconUrl to IconFile, but ended up building with a nuget too old to support IconFile 😢
There these duplicates of each other? https://github.com/aspnet/Extensions/issues/2515. Feel free to close mine if so.
Latest guidance is that we might want both for a transition period (some clients like VS don't respect IconFile yet), but I believe we currently only have IconFile. We can use this to track the idea of adding back IconUrl.
This should be resolved as of 3.1.1
