| Name | Description | |
|---|---|---|
![]() | CacheId | Gets the identifier of the cache that is unique within the scope of the workflow definition.(Inherited from Activity.) |
![]() | CanInduceIdle | Gets or sets a value that indicates whether the activity can cause the workflow to become idle.(Inherited from NativeActivity.) |
![]() | Constraints | |
![]() | DisplayName | Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.(Inherited from Activity.) |
![]() | Id | Gets an identifier that is unique in the scope of the workflow definition.(Inherited from Activity.) |
![]() | Implementation | The execution logic of the activity.(Inherited from NativeActivity.) |
![]() | ImplementationVersion | Gets or sets the implementation version of the activity.(Inherited from NativeActivity.) |
| Name | Description | |
|---|---|---|
![]() | Abort(NativeActivityAbortContext^) | When implemented in a derived class, takes actions in response to the activity being aborted.(Inherited from NativeActivity.) |
![]() ![]() | AddValidationError(NativeActivityContext^, ValidationError^) | Adds a validation error to a list of run-time validation errors that are attached to the execution context. |
![]() | CacheMetadata(ActivityMetadata) | Not implemented. Use the CacheMetadata method instead.(Inherited from NativeActivity.) |
![]() | CacheMetadata(NativeActivityMetadata) | Creates a NativeActivityMetadata object that contains runtime arguments for the workflow validation process.(Overrides NativeActivity::CacheMetadata(NativeActivityMetadata).) |
![]() | Cancel(NativeActivityContext^) | When implemented in a derived class, runs logic to cause graceful early completion of the activity.(Inherited from NativeActivity.) |
![]() | Equals(Object^) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Execute(NativeActivityContext^) | Invokes the process that validates an activity.(Overrides NativeActivity::Execute(NativeActivityContext^).) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata^, Activity^) | Raises an event when creating a map for the dynamic update.(Inherited from NativeActivity.) |
![]() | OnCreateDynamicUpdateMap(UpdateMapMetadata^, Activity^) | Raises an event when creating a map for the dynamic update.(Inherited from NativeActivity.) |
![]() | OnExecute(NativeActivityContext^, Object^, ValidationContext^) | When implemented by a derived class, validates the specified object using the specified native activity and validation contexts. |
![]() | ShouldSerializeDisplayName() | Indicates whether the DisplayName property should be serialized.(Inherited from Activity.) |
![]() | ToString() | Returns a String that contains the Id and DisplayName of the Activity.(Inherited from Activity.) |
![]() | UpdateInstance(NativeActivityUpdateContext^) | Updates the instance of NativeActivity.(Inherited from NativeActivity.) |
| Name | Description | |
|---|---|---|
![]() ![]() | ValidationErrorListPropertyName | The name for an activity constraint property that is a list of workflow run-time validation errors. |
