WindowsRuntimeSystemExtensions.GetAwaiter<(Of <(TResult, TProgress>)>) Method (<(Of <(TResult, TProgress>)>))
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.

this IAsyncOperationWithProgress<TResult, TProgress> source
)
Type Parameters
- TResult
The type of object that returns the result of the asynchronous operation.
- TProgress
The type of object that provides data that indicates progress.
Parameters
