I set the Icon Url using the nuget properties of my .csproj in Visual Studio for Mac. However, when I deploy it to Azure Artifacts (which is like nuget.org), no image icon appears. I am also deploying using Azure Pipelines. I've also tried clearing my cache but no success.
The Azure Artifacts web UI doesn't display package icons at this time.
After a recent server-side change, icons specified via IconUrl should now appear in clients that support them (such as regular Visual Studio; not sure about VS for Mac).
