Event-based Asynchronous Pattern (EAP)

  • Article

There are a number of ways to expose asynchronous features to client code. The Event-based Asynchronous Pattern prescribes one way for classes to present asynchronous behavior.

Note

Starting with .NET Framework 4, the Task Parallel Library provides a new model for asynchronous and parallel programming. For more information, see Task Parallel Library (TPL) and Task-based Asynchronous Pattern (TAP).

In This Section

Event-based Asynchronous Pattern Overview
Describes how the Event-based Asynchronous Pattern makes available the advantages of multithreaded applications while hiding many of the complex issues inherent in multithreaded design.

Implementing the Event-based Asynchronous Pattern
Describes the standardized way to package a class that has asynchronous features.

Best Practices for Implementing the Event-based Asynchronous Pattern
Describes the requirements for exposing asynchronous features according to the Event-based Asynchronous Pattern.

Deciding When to Implement the Event-based Asynchronous Pattern
Describes how to determine when you should choose to implement the Event-based Asynchronous Pattern instead of the IAsyncResult pattern represented by the Asynchronous Programming Model (APM)

How to: Implement a Component That Supports the Event-based Asynchronous Pattern
Describes how to create a component that implements the Event-based Asynchronous Pattern. It is implemented using helper classes from the System.ComponentModel namespace, which ensures that the component works correctly under any application model.

How to: Implement a Client of the Event-based Asynchronous Pattern
Describes how to create a client that uses a component that implements the Event-based Asynchronous Pattern.

How to: Use Components That Support the Event-based Asynchronous Pattern
Describes how to use a component that supports the Event-based Asynchronous Pattern.
