I'm having a little trouble understaing how I would use covariance and contravariance in the real world.

So far, the only example's I've seen have been the same old array example.

object[] objectArray = new string[] { "string 1", "string 2" };

It would be nice to see an example that would allow me to use it during my development if I could see it being used elsewhere.

Can anyone point me to some useful resources?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
