AsyncInfo.Run(Of TResult, TProgress) Method (Func(Of CancellationToken, IProgress(Of TProgress), Task(Of TResult)))
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.

Type Parameters
- TResult
The type that returns the result.
- TProgress
The type that is used for progress notifications.
Parameters
- taskProvider
- Type: System.Func(Of CancellationToken, IProgress(Of TProgress), Task(Of TResult))
A delegate that represents the function that creates and starts the task. The started task is represented by the Windows Runtime asynchronous action that is returned. The function is passed a cancellation token that the task can monitor to be notified of cancellation requests, and an interface for reporting progress; you can ignore either or both of these arguments if your task does not support progress reporting or cancellation.
Return Value
Type: IAsyncOperationWithProgress(Of TResult, TProgress)A started Windows.Foundation.IAsyncOperationWithProgress<TResult,TProgress> instance that represents the task that is generated by taskProvider.
