Q:

How to separate Class Library into multiple assembly (*.dll)? 

I build a class library project with separate class by folder. 
Example:

TEST

Security
Converter
Utility

After I compile project, I will have TEST.dll
but I want TEST.dll, TEST.Security.dll, TEST.Converter.dll, & TEST.Utility.dll
Note:  Security, Converter, Utility is folder in TEST project.  In each folder have c# class. 
How to do? 

A:

Create separate projects for each
Example:

name project TEST.Security class library
name project  TEST.Converter class library
name project  TEST.Utility class library
