Syntaxe

'Declaration
Public Shared Function FromAsyncPattern(Of T1) ( _
    begin As Func(Of T1, AsyncCallback, Object, IAsyncResult), _
    end As Action(Of IAsyncResult) _
) As Func(Of T1, IObservable(Of Unit))

'Usage
Dim begin As Func(Of T1, AsyncCallback, Object, IAsyncResult)
Dim end As Action(Of IAsyncResult)
Dim returnValue As Func(Of T1, IObservable(Of Unit))

returnValue = Observable.FromAsyncPattern(begin, _
    end)

public static Func<T1, IObservable<Unit>> FromAsyncPattern<T1>(
    Func<T1, AsyncCallback, Object, IAsyncResult> begin,
    Action<IAsyncResult> end
)

public:
generic<typename T1>
static Func<T1, IObservable<Unit>^>^ FromAsyncPattern(
    Func<T1, AsyncCallback^, Object^, IAsyncResult^>^ begin, 
    Action<IAsyncResult^>^ end
)

static member FromAsyncPattern : 
        begin:Func<'T1, AsyncCallback, Object, IAsyncResult> * 
        end:Action<IAsyncResult> -> Func<'T1, IObservable<Unit>>

JScript does not support generic types and methods.
