Had an issue during deploy - but it might be just me not understanding core correctly. When setting up a deploy in Azure Devops static Umbraco files in root Umbraco folder does not get added to deploy artifact unless you do both a build and a publish task. I thought I read somewhere that

dotnet publish

also does restore and build, but the target in Umbraco that copies root Umbraco folder to output only runs if you do

dotnet build
