I'm using the latest ASP.net Core bits (1.0.0-preview2-final with Visual Studio Update 3) and the Add > New Scafolded Item seems to have gone for the 'Web Application' template.
It was there in RC2.
I've seen this SO post saying that you need to add following line in project.json under dependencies.
"Microsoft.VisualStudio.Web.CodeGenerators.Mvc": "1.0.0-preview2-final",
"Microsoft.VisualStudio.Web.CodeGeneration.Tools": "1.0.0-preview2-final"
Also, add following under tools
"Microsoft.VisualStudio.Web.CodeGeneration.Tools": "1.0.0-preview2-final"
If I do this, it does expose the UI, but I get "Version for package 'Microsoft.VisualStudio.Web.CodeGeneration.Tools' could not be resolved" when I click OK.
Ideas / workarounds?
