I haven't had the need to override the .Equals implementation on reference types all that much in my coding career. However, such a need sprang up earlier on today. While implementing it in the most rudimentary way, I just couldn't shake the feeling there was something that just didn't feel right. So I booted up Good 'ol Google and took a quick look at what was out there.
I came across this article that spells it out quite nicely (be sure to read the comments as well). Bottom line, if you are dealing with a reference type, its better to include an additional method on your public interface that will compare the contents for equality.
It's still a bit of a gray area for me. I am going to have to sit a while and mull over just what exactly the implications are, but these little bits of information are great to have stored in the back of your mind.
