Does RTC Client API work with Visual Studio 2005 ?

I tried to use RTC Client API with Visual studio 2005 but I cant load its reference,WHY ? . I found it works with Visual Studio 2002. So I have two questions:

1.WHY I cant use it with Visual Studio 2005? and if i can use it soHOW?
2. I tried to preview my webcam but it doesn't work.Also, I wanna askWHY that happened?

Is there something wrong in this Code?

dim myRTC As New RTCClient()
myRTC.Initialize()
dim myCam As RTCCORELib.IVideoWindow
myCam = myRTC.IVideoWindow(RTC_VIDEO_DEVICE.RTCVD_PREVIEW)
myCam.Owner = PictureBox1.Handle.ToInt32
myCam.Visible = True

I hope you can help me in that.
I look forward to hearing from you

Kind regards,
Yasser
