Syntax

public interface IActivity : IOperationResult, IExpando, IDynamicMetaObjectProvider, IIndexable, INotifyPropertyChanged, IInstance<IActivityInfo>, IInstance

Remarks

An activity instance may be executed only once. To execute an activity multiple times, create for each execution an instance and execute it. During the execution, it may be canceled or paused, and also debuggers may be attached to provide development support. The state provide the flags during the execution.

Properties

Arguments

Gets the arguments for the execution.

Declaration

IExpando Arguments { get; }

Property Value

Type	Description
IExpando	The arguments.

Context

Gets the execution context.

Declaration

Property Value

Target

Gets the target against which the activity is executed.
