Just publish modified controllers, models and some parts of a ASP.NET MVC project

Question

If I change my views (.cshtml) or styles (.css) or scripts (.js) in my MVC projects then I can publish it easily by right click on it and select Publish FILE_NAME

If I changed some controllers files or BLL classes or infrastructure classes,

• Which files should be published? which DLLs?

• Of course added references must be published but what are another?

• Should I publish all the DLL files in the bin folder or just some?

• Is there an easy way to VS detect modified files and publish theme by a command or...?

I use FTP method to direct publish and upload our site to the server.

My Publish Preview Step Snapshot:

• What is the name of DLL files that contains the compiled information of controllers, BLL classes and...?

Answer 1

I just published the MVC5Bootstrap-3-1-1-Less.dll and it worked!

So if we uploaded a website and then want only publish the new modified controllers or classes of the MVC web application (here: MVC5) to the server, we should upload the following files:

• MVC5Bootstrap-3-1-1-Less.dll after build
• Added references to the bin folder after build

Here is a image of how publish DLLs of bin folder from Visual Studio:
