Is type casting slow (C#)
It's slower than BaseClassObject as DerivedClass, though, from what I recall, but not significantly.
It's only slower if the conversion fails, as castclass will throw an exception while isinst will simply return null.

Not so much, but the need for it is indicative of a design failure somewhere. Sometimes it's small, or saves a ton of time, or a corner case... but something that tells you to take a second look at the design. Make sure you're stepping outside the norm for a good reason.
