Build Solution :
When we build any solution then Visual studio will build/compile all assemblies (Dlls and EXE’s) that are changed, it is basically incremental or partial process in which only CHANGED assemblies are compiled if there is no changed assemblies it won’t get build
It is full compiled case, in which all assemblies (either changed or not) are deleted and recompiled again, irrespective of changed or not
It is not compile case, it just delete all assemblies (Dlls and EXE’s) from folder but not compiled them again, it remove all compiled files from previous build
Hope you understand this simple article
