i have wpf application sending dataset 25 datatable. not able fix the remote server returned unexpected response: (400) bad request synchronous , asynchronous both. below app.config:

<?xml version="1.0" encoding="utf-8" ?> <configuration>     <system.servicemodel>         <bindings>             <basichttpbinding>                 <binding name="basichttpbinding_icommunication" closetimeout="00:01:00"                     opentimeout="00:01:00" receivetimeout="01:00:00" sendtimeout="01:00:00"                     allowcookies="false" bypassproxyonlocal="false" hostnamecomparisonmode="strongwildcard"                     maxbuffersize="2147483647" maxbufferpoolsize="2147483647" maxreceivedmessagesize="2147483647"                     messageencoding="text" textencoding="utf-8" transfermode="buffered"                     usedefaultwebproxy="true">                   <readerquotas maxdepth="2147483647" maxstringcontentlength="2147483647" maxarraylength="2147483647"                    maxbytesperread="2147483647" maxnametablecharcount="2147483647" />                         <security mode="none">                         <transport clientcredentialtype="none" proxycredentialtype="none"                             realm="" />                         <message clientcredentialtype="username" algorithmsuite="default" />                     </security>                 </binding>             </basichttpbinding>         </bindings>         <client>             <endpoint address="http://localhost:49486/communication.svc"                 binding="basichttpbinding" bindingconfiguration="basichttpbinding_icommunication"                 contract="communicationreference.icommunication" name="basichttpbinding_icommunication" />         </client>     </system.servicemodel> </configuration>

and service's web.config:

<?xml version="1.0"?> <configuration>    <system.web>     <compilation debug="true" targetframework="4.0" />     <httpruntime maxrequestlength="2147483647" executiontimeout="10000"/>   </system.web>   <connectionstrings>     <add name="conname" connectionstring="data source=*******;initial catalog=****; user id=**; password=*****"/>      </connectionstrings>   <system.servicemodel>         <behaviors>             <servicebehaviors>         <behavior>           <!-- avoid disclosing metadata information, set value below false , remove metadata endpoint above before deployment -->           <servicemetadata httpgetenabled="true"/>           <!-- receive exception details in faults debugging purposes, set value below true.  set false before deployment avoid disclosing exception information -->           <servicedebug includeexceptiondetailinfaults="false"/>           <servicethrottling maxconcurrentcalls="100" maxconcurrentsessions="1000" maxconcurrentinstances="1600" />         </behavior>       </servicebehaviors>     </behaviors>         <servicehostingenvironment multiplesitebindingsenabled="true" />   </system.servicemodel>  <system.webserver>     <modules runallmanagedmodulesforallrequests="true"/>   </system.webserver>   </configuration>

p.s.: tested passing blank dataset, working. dataset datatable not working.
