At a very high level C# code comprises of Classes
A namespace is an container for holding related classes
An assembly is an container for related Namespaces
A assembly can be a executable file (EXE) or an DLL (Dynamically Linked Library)
When we compile our application the compiler builds one or more assembly based on how we have partitioned the code
Project vs. Solution
An Project is an set of files that produces an single Assembly (Executable File)
An Solution is an collection of Projects that each generate its own Assemblies
Solution helps to keep track of the dependencies of each project
It also keeps track of the relations between the different project
