Visual Basic .NET Language Task-based asynchronous pattern Basic usage of Async/Await
Example
You can start some slow process in parallel and then collect the results when they are done:
Public Sub Main()
Dim results = Task.WhenAll(SlowCalculation, AnotherSlowCalculation).Result
For Each result In results
Console.WriteLine(result)
Next
End Sub
Async Function SlowCalculation() As Task(Of Integer)
Await Task.Delay(2000)
Return 40
End Function
Async Function AnotherSlowCalculation() As Task(Of Integer)
Await Task.Delay(2000)
Return 60
End Function
After two seconds both the results will be available.
