Yes, those docs need to be updated. The HelloWorld example was changed to include everything in the demo in order that those examples could be easily accessed when a new web app is created. However, you can change the source code in WebAppBuilder to include only the files you want whenever you create a new web project. All of the source code for that (and everything else) is included.
>I have just installed ActiveVFP. I got down to the "Step by step simple example". After I run the WebAppBuilder the instructions say that I should get browser with a "Hello World" example. I don't. I tried several times but I always get the ActiveVFP Demo Page. I know it must be a "simple" reason.
