I think the instructions need to be More detailed in the Docs.
I created a new Application under IIS Manager - at first I created a new App Pool - then reading a post here i switched it back to Default.
Copied all the files, made bin folder with all the DLLS. Put webconfig, default.json, default.html in the root of the application folder.
I get a blank page when brining up the app or I get this error: Do we need o define a handler like we did for Visual Web Gui (.wgx)?
IIS 8.5 Detailed Error - 500.19 - Internal Server Error

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".
