I used the official Aurelia dotnet template and Mads Kristensen’s Nuget package for ASP.NET Core to create PWAs. It seems to work smoothly (I’m a rookie with this) until one upgrades to WebPack 4.0. There’s more at https://github.com/aspnet/JavaScriptServices/issues/1499, together with the problem I encountered with the uprgrade to WebPack 4.0 (don’t do that yet) in case someone is interested about the steps more closely.
