Hello,

What exactly are the differences between a Solution and a Project in Visual Studio? How are they related,

Solution is a collection of projects.

when should a solution contain multiple projects?

When you need to layer your architecure, you usually break them in to projects. (DB, Data access layer, business objects layer, presentation layer, web services layer etc.)
