Multithreaded Programming with the Event-based Asynchronous Pattern

.NET Framework 4.5

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.
