Type Parameters

T1

The type of the first in argument of the activity delegate.

T2

The type of the second in argument of the activity delegate.

T3

The type of the third in argument of the activity delegate.

T4

The type of the fourth in argument of the activity delegate.

TResult

The type of the out argument of the activity delegate.

Remarks

The ActivityDelegate enables activity authors to expose callbacks with specific signatures that users of the activity can provide activity-based handlers for. ActivityFunc<T1,T2,T3,T4,TResult> is an ActivityDelegate that returns a value. The signature of the ActivityFunc<T1,T2,T3,T4,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.
