Multithreaded Programming with the Event-based Asynchronous Pattern

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

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.

• Walkthrough: Implementing a Component That Supports the Event-based Asynchronous Pattern
  Illustrates 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: Use Components That Support the Event-based Asynchronous Pattern
  Describes how to use a component that supports the Event-based Asynchronous Pattern.
