Nearly give up, how to play RTSP / HLS / Smooth Streaming in Visual Basic Language

Question

I know there are so many samples for playing RTSP / HLS / Smooth Streaming, but it really lacks supporting Visual Basic language, i really struggling to convert from C++ / C# into VB without errors, maybe it would be easier if i can find some VB
examples for this situation, i really appreciated any help.. thanks

Hi HiLLzX,
Did you forget to using reference in VB or Import the namespace? See my current code, using Button click can play a test demo. Do not forget to reference SDk in your project.
XAML:
<Page
x:Class="App242.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:App242"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
<Button Content="Button" HorizontalAlignment="Left" Height="88" Margin="52,103,0,0" VerticalAlignment="Top" Width="138" Click="Button_Click"/>
<MediaElement x:Name="mediaElement" HorizontalAlignment="Left" Height="427" Margin="409,127,0,0" VerticalAlignment="Top" Width="800"/>
</Grid>
</Page>
VB:
'using Windows.Media;
Imports Windows.Media
' The Blank Page item template is documented at http://go.microsoft.com/fwlink/?LinkId=234238
''' <summary>
''' An empty page that can be used on its own or navigated to within a Frame.
''' </summary>
Public NotInheritable Class MainPage
Inherits Page
Private extensions As New MediaExtensionManager
Private Sub Button_Click(sender As Object, e As RoutedEventArgs)
mediaElement.Source = New Uri("http://mediadl.microsoft.com/mediadl/iisnet/smoothmedia/Experience/BigBuckBunny_720p.ism/Manifest")
extensions.RegisterByteStreamHandler("Microsoft.Media.AdaptiveStreaming.SmoothByteStreamHandler", ".ism", "text/xml")
extensions.RegisterByteStreamHandler("Microsoft.Media.AdaptiveStreaming.SmoothByteStreamHandler", ".ism", "application/vnd.ms-sstr+xml")
mediaElement.Play()
End Sub
End Class
