uploading large xml to WCF REST service -> 400 Bad request - wpf

Question

I have been trying to search for this error but no luck so far.
So I have a service on my client with this web.config
<system.serviceModel>
<serviceHostingEnvironment>
<baseAddressPrefixFilters>
<add prefix="http://www.mywebsite.com/"/>
</baseAddressPrefixFilters>
</serviceHostingEnvironment>
<services>
<service behaviorConfiguration="ServiceBehavior" name="UploadService">
<endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
contract="IUploadService">
<identity>
<dns value="http://www.mywebsites.com/" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="ServiceBehavior" maxReceivedMessageSize="4194304">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
and on the client I have this configuration
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="WSHttpBinding_IUploadService" closeTimeout="00:01:00"
openTimeout="00:01:00" receiveTimeout="00:30:00" sendTimeout="00:30:00"
bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"
maxBufferPoolSize="524288" maxReceivedMessageSize="4194304"
messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
allowCookies="false">
<readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
<reliableSession ordered="true" inactivityTimeout="00:30:00"
enabled="false" />
<security mode="Message">
<transport clientCredentialType="Windows" proxyCredentialType="None"
realm="">
<extendedProtectionPolicy policyEnforcement="Never" />
</transport>
<message clientCredentialType="Windows" negotiateServiceCredential="true"
algorithmSuite="Default" establishSecurityContext="true" />
</security>
</binding>
</wsHttpBinding>
</bindings>
<client>
<endpoint address="http://www.mywebsite.com/UploadService.svc"
binding="basicHttpBinding" bindingConfiguration="" contract="IUploadService"
name="WSHttpBinding_IUploadService">
<identity>
<dns value="http://www.mywebsite.com/" />
</identity>
</endpoint>
</client>
and I am uploading the files like this :-
using (Stream stream = new FileStream(strFilePath, FileMode.Open, FileAccess.Read))
{
try
{
using (UploadServiceClient upc = new UploadServiceClient())
{
upc.UploadFile(stream);
}
}
catch (Exception exc)
{
}
}
for small files it works fine, but for large XML files, this failes with 400 Bad Request. What I can do to change these settings to get large XML file to transfer?
Thanks for your help and time

You should to see if the service has the same maxReceivedMessageSize="4194304" as the client and if the XML is indeed smaller than the 4,194,304 byte limit that is set. WCF defaults to a maxReceivedMessageSize of 64K.
UPDATE:
I noticed your config shows the client being configured for basicHttpBinding but the config only shows a wsHttpBinding. The wsHttpBinding config would be ignored by WCF since it doesn't pertain to basicHttpBinding. If the client config file doesn't have a basicHttpBinding element then in .NET 4 a default one is being used. If this is true then you'll run into the 64K limit described above.
