Adding an appsetting to the root web.config file in a helix solution

Question

We are trying to figure out how to add an appsetting into the root websites web.config from a helix feature project. Its my understanding that if you add a transform file e.g (web.config.transform) into the root of your feature project and build the project using the helix gulp script, the transform should update the root config. Is this correct? Unfortunately when we run the gulp script we get an error

    [11:26:54] Starting '04-Apply-Xml-Transform'...
[11:26:55] Applying configuration transform: D:\Projects\xxxxxxx\src\Feature\Claims\code\xxxxx.Website.Feature.Claim\App_Config\Include\Web.config.transform

It looks to me as like it is trying to update a local web.config.

Answer 1

Your web.config would not reside here C:\inetpub\wwwroot\xxxxxxxxx\website\xxxxxxx.Website.Feature.Claim\App_Config\Include\Web.config

It would reside here: C:\inetpub\wwwroot\xxxxxxxxx\website\Web.config
