Understanding the concept of projects and solutions is central to success with Microsoft Visual Studio .NET. We presented these concepts in Chapter 2 and then moved on to discuss other features of the IDE and how to extend the IDE through macros and add-ins. In this chapter, we'll look at how to customize and use projects and solutions in advanced scenarios. We'll build projects and solutions from the command line, and we'll talk about using Microsoft Visual SourceSafe (VSS) for source code management.
