[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Represents the status of an asynchronous operation.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

type IAsyncResult =  interface end

The IAsyncResult interface is implemented by classes containing methods that can operate asynchronously. It is the return type of methods that initiate an asynchronous operation, and it is passed to methods that conclude an asynchronous operation.

An object that supports the IAsyncResult interface stores state information for an asynchronous operation and provides a synchronization object to allow threads to be signaled when the operation completes.
