Through this question Methods of Visual Studio Publishing I've discovered how to publish specific files through Visual Studio. I can select the files I want to publish, right click and select the "Publish selected files" option or use the shortcut keys.
When I do this, .cs files are posted to the server, but they need to be converted to DLL, correct? How do I do that? Am I posting correctly?
Another thing I noticed was that in my project, I do not have a DLL for each code-behind.
Note: I use Visual Studio 2013.
