Default target framework of Office Addins template should be ASP.NET Core
Currently, the default solution of an Office Addins generates two projects that targets .NET Framework 4.6.x. Microsoft should change it to ASP.NET Core. There is a way to adapt the manifest file as seem in https://stackoverflow.com/questions/53991876/change-target-framework-of-a-office-addins-project-from-net-framework-to-net-c/53993432 , but It would be great if the keyword ~remoteAppUrl could refer to another address.
I see this might be a problem as .NET Core is optional when installing VS and might escalate to a broader discusstion.
