Creation of Websocket server in c#

Question

Hi,
 
I want to create a websocket server in c# and HTML5 browser is my client. I want to send string text and a XML file from server to client via websocket. 
I got some code from internet but that code is not much useful for me. I got stuck into this so can anybody help me to resolve this as early as possible.
 
Configurations : 
1. Visual Studio 2010
2. Dot Net framework 4.0
3. Windows 7 and 32bit o.s
 

Thank you in advance.
