Whenever I try to throw a new FaultException(Of MyFault)(myFaultInstance) from my service implementation, I receive the following exception: 'Unspecified ServiceModel Fault'. I have the FaultContract specified in the service contract on both the service and client. I'm getting this exception on the service side.
Thanks.

on the client side,we are able to detect right fault ,but for some reason fault reason and message is not serialized properly.

My problem was as defined in the link http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=416668&SiteID=1
Also the solution is defined there. It is Visual Studio Configuration issue.

Now I am getting this error. I have win ui for both server and client side.
I did not get clear from the above thread what was the solution.
Thanks,

If possible,can you please share your service code and config and client code and config
-Thank you

Detail object has your fault object information,so you can access Detail object to access all your fault contract obeject data
Example:
Try
Catch ex As FaultException(Of RequestEmployeesFault)
Console.WriteLine(ex.Detail.DetailedReasonProperty.ToString())
End try
'I modified your code ltl bit (I am not vb expert,so just to simplify)

I had tried this with and without the behaviors section in the service config. When running this example in VS, I get an unhandled exception when I tried to throw the FaultException. In VS I view detail of this exception and the message is "Unspecified ServiceModel Fault".
