AsyncInfo Class

  • Article

For apps that target Windows Phone OS 7.0 and 7.1, do not use any members of this type in your app. If you do, your code will throw a MethodAccessException. This type is security-critical, which restricts it to internal use by the .NET Framework for Windows Phone class library.

Provides factory methods to construct representations of managed tasks that are compatible with Windows Runtime asynchronous actions and operations.

This API is not CLS-compliant.

Methods

  Name Description
Run(Func<(Of <(CancellationToken, Task>)>)) Creates and starts a Windows Runtime asynchronous action by using a function that generates a started task. The task can support cancellation.
Run<(Of <(TResult>)>)(Func<(Of <(CancellationToken, Task<(Of <(TResult>)>)>)>)) Creates and starts a Windows Runtime asynchronous operation by using a function that generates a started task that returns results. The task can support cancellation.
Run<(Of <(TProgress>)>)(Func<(Of <(CancellationToken, IProgress<(Of <(TProgress>)>), Task>)>)) Creates and starts a Windows Runtime asynchronous action that includes progress updates, by using a function that generates a started task. The task can support cancellation and progress reporting.
Run<(Of <(TResult, TProgress>)>)(Func<(Of <(CancellationToken, IProgress<(Of <(TProgress>)>), Task<(Of <(TResult>)>)>)>)) Creates and starts a Windows Runtime asynchronous operation that includes progress updates, by using a function that generates a started task that returns results. The task can support cancellation and progress reporting.
