Build Solution
When
we build an application using Visual Studio that time it will build only those
files which have changed/modified. The files
which are not changed/modified Will not build.
Clean Solution
The
clean solution are use to delete all the compiled DLLs and EXE files from
bin/obj application directories.
Rebuild
Solution
When
we Rebuild an application using Visual Studio that time deleted all complied
like DLLs and EXE files and after that build all the files which are
changed/modified or not.
It is a combination of both clean and Build.
i.e. (CLEAN + BUILD)
