Indicates to the workflow runtime that the currently executing activity should transition to the Closed state. |
| Equals(Object) |
Determines whether the specified object is equal to the current object. (Inherited from Object) |
| ExecuteActivity(Activity) |
Called by a composite activity to schedule the execution of a child activity. The workflow runtime disallows execution of a child activity that is not in the initialized state. |
| GetHashCode() |
Serves as the default hash function. (Inherited from Object) |
| GetService(Type) |
Returns a service of the specified type. |
| GetService<T>() |
