The "DotNetNuke 4.8.0 Install" download is described as:

"Contains only the files needed for a run-time deployment to a web server"

And yet it's filled with source code files.  I don't understand that at all.  It was necessary for me to modify some source for my site, and everything was working fine locally, so I decided to build the solution, and upload the new dll's.  Ater hours and hours trying to find out why my changes weren't working, I realized it's because my DNN site is ignoring my shiny new DLL's because it is compiling the .vb files from the install kit.  At least that's the only thing I can figure.  Worse, when I deleted all the source files from my site, it no longer runs at all.  Anyone have tips on how to compile from source and deploy WITHOUT the source files?

Thanks.

Thank you for the explanation.  I eventually gave up on trying to compile the UI layer, and just dropped my modified VB files into the website which worked.  But it's good to hear some confirmation of what I learned the hard way.  Thank you!
