Where is the clean build/rebuild feature in Unity?

This feature is required because Unity is sometimes unable to tell that the source files have changed.
How do I tell Unity to reread source files and rebuild so it can build the up to date version instead of having to shut it down and reopen so it will try to read the most recent version of the source files from the disk?

Build from Visual Studio instead, then you know for a fact it has built.

I don’t think building from visual studio gaurante the editor version is up to date?

Tools → Options → Tools for Unity → Miscellaneous / Disable the full build of projects

  1. Set the option to FALSE
  2. Restart Visual Studio
