WCF (400) Bad Request error

Hi,

I have a web service which i am calling with varying amounts of data. when i pass smaller amounts of data it works fine, but when i pass more i get the (400) Bad Request error. The memory footprint of my whole app in taskmanager is ~44mb which doesn't seem excessive to me.

I am running the app in this configuration - Solution file with 3 projects:

1 - wcf web service (published and running on local iis)
2 - class library with the reference to the web service
3 - test windows forms project to call the class library

i have set these values in the web.config of the service project

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IPeService" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            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/PeService/PeService.svc"
          binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IPeService"
          contract="PeService.IPeService" name="BasicHttpBinding_IPeService" />
    </client>
    <behaviors>
      <serviceBehaviors>

Open in new window

and copied the same values into the app.config of both the other projects.

Can somebody enlighten me as to why i cannot pass the extra data?

thanks for replying, i cant find anything there that solves the issue, however i noticed that if i delete my app.config file and regenerate it by refreshing the service reference in VS i get default values for all the max sizes instead of the values i've specified in the web.config file.

Does anybody know why this is?

check with fiddler if there is something wrong.

how can i do this?

I have been checking the request and it looks fine (just more information in the soap envelope when send data)

Or do you mean check the response when generating the config?

i get this response error:

HTTP/1.1 415 Cannot process the message because the content type 'application/soap+xml; charset=utf-8' was not the expected type 'text/xml; charset=utf-8'.

on this call when updating the service:

POST http://localhost./peservice/Peservice.svc/mex HTTP/1.1
