Summary

Today you learned how to use Visual SourceSafe and its tools in the Visual Studio .NET IDE. By putting your projects under source control, you have the benefit of knowing your source code is safe from accidental deletion of files and in a durable data store that can be backed up for archive purposes. By diligently checking in files after you've worked with them, you can build up a version history of your application's files. This enables you to roll back changes or even complete installations of applications with a few clicks of the mouse. In a team development environment, SourceSafe should be a requirement. If you're a single developer working alone on projects, you should always use SourceSafe to keep track of changes made to your code.

You've just about completed all 21 days of learning Visual Studio .NET. Tomorrow, on Day 21, you learn how to implement object role modeling using Visio.
