c# - What is the difference between a "build" and a "rebuild" in Visual Studio?

Question

I do not know if i understood right , the difference between a "build" and "rebuild" command of a project in Visual Studio is the fact that a build only compiles the code which was changed , since a "rebuild" command compiles all the code from project regardless is it was changed or not.

Also a rebuild command includes a clean of the project, since build command does not ?

Please advice me to understand better these differences.

Thanks !

You have identified the fundamental difference.

Build will look at the files that have been modified since the last successful compile and link and just compile those and then link the result.

Rebuild will recompile everything.

Strictly speaking it might be different to a clean (which removes the intermediate and output files) and build and just recompile everything, but the result should be the same. However, there may be cases that fail (see Femaref's comment).
