 # Deciding When to Implement the Event-based Asynchronous Pattern
 The Event-based Asynchronous Pattern provides a pattern for exposing the asynchronous behavior of a class. With the introduction of this pattern, the [!INCLUDE[dnprdnshort](../../../includes/dnprdnshort-md.md)] defines two patterns for exposing asynchronous behavior: the Asynchronous Pattern based on the <xref:System.IAsyncResult?displayProperty=nameWithType> interface, and the event-based pattern. This topic describes when it is appropriate for you to implement both patterns.  
 
- For more information about asynchronous programming with the <xref:System.IAsyncResult> interface, see [Event-based Asynchronous Pattern (EAP)](../../../docs/standard/asynchronous-programming-patterns/event-based-asynchronous-pattern-eap.md).  
+ For more information about asynchronous programming with the <xref:System.IAsyncResult> interface, see [Asynchronous Programming Model (APM)](../../../docs/standard/asynchronous-programming-patterns/asynchronous-programming-model-apm.md).  
 
 ## General Principles  
  In general, you should expose asynchronous features using the Event-based Asynchronous Pattern whenever possible. However, there are some requirements that the event-based pattern cannot meet. In those cases, you may need to implement the <xref:System.IAsyncResult> pattern in addition to the event-based pattern.
