Puede usar este método de delegado con el método estático SPLongOperation.Begin(SPLongOperation.BeginOperation) , tal como se muestra en el ejemplo siguiente:

SPLongOperation.Begin(
    delegate(SPLongOperation longOperation)
    {
        // Do something that takes a long time to complete.
        
        
        // Inform the server that the work is done
        // and that the page used to indicate progress
        // is no longer needed.
        longOperation.End("default.aspx");
    }
);

' Do something that takes a long time to complete.
' Inform the server that the work is done
' and that the page used to indicate progress
' is no longer needed.
SPLongOperation.Begin(Function(longOperation) AnonymousMethod1(longOperation))
