Dear all, this is the problem i am facing since last 2 days. Please give me a solution asap..Thanks in advance

Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service.

I am getting the error while doing the ado.net application through wcf. My application is posted in iis 5.1.. I am getting this error while creating a client for the hosted wcf service.. What steps I need to follow to solve this issue....

Update the reference to create a latest proxy. Did it work at least once?
Try creating a proxy with svcutil.exe. Although it's not different, but at least we can eliminate if its VS proxy generation configuration which is causing it. If the service is up then there is no real reason for VS not being able to create a proxy. And if you are developing in VS, can you try using the ASP.net development web server to run it.

Also, check if you can create and run the default WCF service in the web section of File -> New -> Project menu.

I tried in ASP.net Webserver. It is working fine in wcftestclient when i used the URL generated by ASP.net Webserver . The values are saving inside the database.
