LabManagerSoap.VMwareLabManagerSOAPinterface showing error

Hi,

This the first time i'm trying to use the lab manager SOAP api's provided and i have least knowledge on the said area.

I was going through the LM api documentation :http://www.vmware.com/pdf/labmanager_SOAP_API_Guide.pdf

I'm using VS 2010. I have followed the exact steps mentioned in the documentation:

1. Created a console project with C#

2. successfully Added  lab manager web reference

3. i copied the sample program to program.cs file

LabManagerSoap.VMwareLabManagerSOAPinterface shows the following error.

Can anyone help me regaring this?

Error 1: The type or namespace name 'VMwareLabManagerSOAPinterface' does not exist in the namespace 'ConsoleApplication1.LabManagerSoap' (are you missing an assembly reference?)

Thanks,

Raj
