WindowsRuntimeSystemExtensions Class
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.

The WindowsRuntimeSystemExtensions type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | AsAsyncAction | Returns a Windows Runtime asynchronous action that represents a started task. |
![]() ![]() | AsAsyncOperation(Of TResult) | Returns a Windows Runtime asynchronous operation that represents a started task that returns a result. |
![]() ![]() | AsTask(IAsyncAction) | Returns a task that represents a Windows Runtime asynchronous action. |
![]() ![]() | AsTask(IAsyncAction, CancellationToken) | Returns a task that represents a Windows Runtime asynchronous action that can be cancelled. |
![]() ![]() | AsTask(Of TProgress)(IAsyncActionWithProgress(Of TProgress)) | Returns a task that represents a Windows Runtime asynchronous action. |
![]() ![]() | AsTask(Of TResult)(IAsyncOperation(Of TResult)) | Returns a task that represents a Windows Runtime asynchronous operation returns a result. |
![]() ![]() | AsTask(Of TProgress)(IAsyncActionWithProgress(Of TProgress), IProgress(Of TProgress)) | Returns a task that represents a Windows Runtime asynchronous action that reports progress. |
![]() ![]() | AsTask(Of TProgress)(IAsyncActionWithProgress(Of TProgress), CancellationToken) | Returns a task that represents a Windows Runtime asynchronous action that can be cancelled. |
![]() ![]() | AsTask(Of TResult)(IAsyncOperation(Of TResult), CancellationToken) | Returns a task that represents a Windows Runtime asynchronous operation that returns a result and can be cancelled. |
![]() ![]() | AsTask(Of TProgress)(IAsyncActionWithProgress(Of TProgress), CancellationToken, IProgress(Of TProgress)) | Returns a task that represents a Windows Runtime asynchronous action that reports progress and can be cancelled. |
![]() ![]() | AsTask(Of TResult, TProgress)(IAsyncOperationWithProgress(Of TResult, TProgress)) | Returns a task that represents a Windows Runtime asynchronous operation returns a result. |
![]() ![]() | AsTask(Of TResult, TProgress)(IAsyncOperationWithProgress(Of TResult, TProgress), IProgress(Of TProgress)) | Returns a task that represents Windows Runtime asynchronous operation that returns a result and reports progress. |
![]() ![]() | AsTask(Of TResult, TProgress)(IAsyncOperationWithProgress(Of TResult, TProgress), CancellationToken) | Returns a task that represents a Windows Runtime asynchronous operation that returns a result and can be cancelled. |
![]() ![]() | AsTask(Of TResult, TProgress)(IAsyncOperationWithProgress(Of TResult, TProgress), CancellationToken, IProgress(Of TProgress)) | Returns a task that represents a Windows Runtime asynchronous operation that returns a result, reports progress, and can be cancelled. |
![]() ![]() | GetAwaiter(IAsyncAction) | Infrastructure. Returns an object that awaits an asynchronous action. |
![]() ![]() | GetAwaiter(Of TProgress)(IAsyncActionWithProgress(Of TProgress)) | Infrastructure. Returns an object that awaits an asynchronous action that reports progress. |
![]() ![]() | GetAwaiter(Of TResult)(IAsyncOperation(Of TResult)) | Infrastructure. Returns an object that awaits an asynchronous operation that returns a result. |
![]() ![]() | GetAwaiter(Of TResult, TProgress)(IAsyncOperationWithProgress(Of TResult, TProgress)) | Infrastructure. Returns an object that awaits an asynchronous operation that reports progress and returns a result. |
