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.
[SECURITY CRITICAL]
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Provides extension methods for converting between tasks and Windows Runtime asynchronous actions and operations.
This API is not CLS-compliant.

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 <(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. |
