The West Michigan Day of .Net had some good talks. I really enjoyed the advice Josh Holmes had on always having a 2-5 year plan. It is the basis to his success and was a great motivator.
He also discussed three things you should never bring into the workplace:
1. Sex
2. Religion
3. Politics
His power point had some good quotes like "Eat like a bird poop like an elephant." Good advice.
An interesting aspect of C# that I have never heard of was yield return method which basically maintains the state of objects returned by a method.
Here is an article that explains it.
The coolest thing I learned was about Microsoft's Empower Program. It gives a Premium MSDN Subscription and 5 internal + 5 client licenses for a wooping $375 for the first two years! This is great for MISVS which only have 1-5 developers.
To top the conference off, I won a book on Software Estimation.
