I get MSDN Mag every month and it has been a while since I've read an article that really catches my attention.  The new stuff is interesting but I am reading them for informational purposes only because I'm not currently using them.

This month the CLR Inside Out column has a great article on collection best practices.  This is a topic that most developers can use immediately.  Even if you know this stuff it doesn't hurt to get a refresher every now and then.  Plus, it can reaffirm what you already knew or remind you of something you may have forgotten about.

• When to Create a Custom Collection
• Existing Collections
• Generic or Non-Generic
• Performance Implications
• Collection Interfaces
• A Family Tree - Good tips on working with collections and their relationships.

Giddy Up!
