CREATING DDL
------------------------------------------------------------------------

Class Library(.NET standard) is the template for .ddl library.

if you want to upload the library on NuGet you need to create a project
selecting the Class Library. Dx on the name of solution and go to "Properties"
->Package-> check "Generate Nuget package on build".

go to "Properties"->"Build"->"Output path"-> select the folder where 
you want the local NuGet library stays. 

then simply build the project.

In the client program where you want to use the library just go on 
dx solution->"Nuget Package manage"-> Package source -> button in the right
and configure a new location for getting local NuGet source.

STATIC LIBRARY
------------------------------------------------------------------------
Static library is a library that is linked before the creation of executable 
file, and it is somehow integrated to the source code.
It's an operation of reorganization and copy paste to the source code to create
a stand alone file.

SHARED LIBRARY
------------------------------------------------------------------------
Shared library is a library that are shared by EXECUTABLE FILES, so 
multiple programs uses the same modules without copying it. 
They are loaded when the first client program is lunched.

The modern OS treats them as a executable program.

DYNAMIC-LINK LIBRARY (DDL, WINDOWS) OR DYNAMIC SHARED OBJECT(DSO, Unix-Like)
----------------------------------------------------------------------------
The linker does litte work in the creation of a prograrm but the major is 
done in the loading or in run-time(Done by the linker that's part of the 
OS).
