.Net 4.0 WCF service error passing parameters

Question

I am trying to test the WCF service using the basichttpbinding endpoint from the WCF test client. I can check the methods with which I do not pass parameters without problems, but when I need to pass a parameter, I get the following error:

Failed to call the service. Possible reasons: the service is disabled or unavailable; client side configuration does not match proxy; existing proxy is invalid. Refer to the stack trace in detail. You can try to restore the launch of a new proxy server, restore the default setting, or update the service.

An error occurred while executing the command definition. See Internal Exception for details.

Answer 1

... WCF !:)

Answer 2

- , [DataContract] [Serializable] SelectClientSearch_Result.

Answer 3

, web.config :

<serviceHostingEnvironment>
    <baseAddressPrefixFilters>
        <add prefix="http://host:port"/>
    </baseAddressPrefixFilters>
</serviceHostingEnvironment>

If this does not work, you can try adding the above and removing the elements: <host></host>(idea from the last link that I linked)

Just adding the following to web.config can help.

<system.serviceModel>        
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />    
</system.serviceModel>

I read the following sites:

http://msdn.microsoft.com/en-us/library/ms731336.aspx
http://community.discountasp.net/showthread.php?t=7719

One mentioned that the WCF service behaves exactly the same as the ASMX service, so I thought it might be relevant.
