I dun know if any1 ever face this same Problem as me when publishing and

The WebService can also consumed without error from another VB.Net applications

However, when I deployed and published it to run on the IIS Web Server as follows :-
 C:\Inetpub\wwwroot\ProductWS\ProdService.asmx
and run the WebService on browser from the IIS Server
(http://localhost/ProductWS/ProdService.asmx), it return the following errors:-

Any1 encountered such problem and know the solution? pls advise me.

hi thanks... i just realized for ur hint... I am using the wrong version of ASP.NET in my IIS server..

The Web Service was created with ASP.NET version 2.xxxx, but the IIS Server is still referencing to ASP.NET version 1.xxxx....

I fixed it and it works..

Thanks. :>
