I am working on wcf application in which I want upload and download large files in local network. but I got failed exception as "400 bad request".

this is server side config file as below

<configuration>
	<system.servicemodel>
    
    
		<services>
   <service behaviorconfiguration="TransferServiceBehavior" name="WcfTransferTest.transfer">
    <endpoint address="transfer" binding="basicHttpBinding" bindingconfiguration="TransferService">

this is client side config file as below

<configuration>
    <system.servicemodel>

      <behaviors />

        </basichttpbinding>
      </bindings>

      <client>
        <endpoint address="http://localhost:3778/transfer.svc/transfer">
          binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_Itransfer"
          contract="FileService.Itransfer" name="BasicHttpBinding_Itransfer" />
      </endpoint></client>
      
    </system.servicemodel>
</configuration>

when I set client side transferMode to buffered it can upload small file like KB, and show error when file more than 1MB . but it does not make sense , because I set transferMode to Streamed on server side, and client should be same.
when client and service both set to streamed , I receive "bad request 400" . it took my two day and I tried many suggestions , people said it works for them , but mine is not.

in my code chunk Size is 65000.

please tell me concrete answer , like which parameter in config file is got wrong.
could anyone tell me how to fix this error? I tried many solution, maybe I am missing something here.
how can fix that in order to upload large file through basicHttpBinding with Streamed mode?

thanks in advance!
