Namespace:System.Reactive.Linq
Versammlung: System.Reactive (in System.Reactive.dll)

Syntax

'Declaration
Public Shared Function FromAsyncPattern(Of TResult) ( _
    begin As Func(Of AsyncCallback, Object, IAsyncResult), _

) As Func(Of IObservable(Of TResult))
'Usage
Dim begin As Func(Of AsyncCallback, Object, IAsyncResult)
