- 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<TResult> is an ActivityDelegate that returns a value. The signature of the ActivityFunc<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.
Constructors
| ActivityFunc<TResult>() |
Creates a new instance of the ActivityFunc<TResult> class. |
Properties
| DisplayName |
Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking. (Inherited from ActivityDelegate) |
| Handler |
Gets or sets the activity that is represented by this ActivityDelegate. (Inherited from ActivityDelegate) |
| Result |
Gets or sets the out argument of the activity delegate. |
Methods
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetResultArgument() |
When implemented in a derived class, returns the DelegateOutArgument of the ActivityDelegate. (Inherited from ActivityDelegate) |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
| OnGetRuntimeDelegateArguments(IList<RuntimeDelegateArgument>) |
Supplies a list of runtime arguments for the ActivityDelegate. (Inherited from ActivityDelegate) |
| ShouldSerializeDisplayName() |
Indicates whether the DisplayName property value should be serialized to XAML. (Inherited from ActivityDelegate) |
| ToString() |
Returns a String representation of the ActivityDelegate that contains the DisplayName. (Inherited from ActivityDelegate) |
