The type of the out argument of the activity delegate.

Inheritance
Object
ActivityDelegate
ActivityFunc<T,TResult>

Remarks

The ActivityDelegate enables activity authors to expose callbacks with specific signatures that users of the activity can provide activity-based handlers for. ActivityFunc<T,TResult> is an ActivityDelegate that returns a value. The signature of the ActivityFunc<T,TResult> is specified as generic type arguments.

There are multiple generic versions of this type that take from 1 to 16 in arguments, plus the out argument, for the activity that is called. There are also ActivityAction types for activity delegates that do not return values.
