| * `Action<>` is used when there is a need to perform an action using the arguments of the delegate. | ||
| * `Func<>` is used usually when you have a transformation on hand, that is, you need to transform the arguments of the delegate into a different result. Projections are a prime example of this. | ||
| * `Predicate<>` is used when you need to determine if the argument satisfies the condition of the delegate. It can also be written as a `Func<T, bool>`. | ||
| * `Action<>` is used when there is a need to perform an action using the arguments of the delegate. The method it encapsulates does not return a value. |

I think it's a good idea to add the return values to the definitions here. I'm not 100% sure that "encapsulates" is technically accurate, since the method is assigned to the delegate type. @BillWagner Can you comment if "encapsulates" is correct here?

Yes, I agree that we need some more insight into that if it creates confusion. To be honest, I was using msdn docs referring to these particular delegates :).
