The maximum string content length quota (8192)

I have web application which calls WFC service, but I am getting the
following error:



The maximum string content length quota (8192) has been exceeded while
reading XML data. This quota may be increased by changing the
MaxStringContentLength property on the XmlDictionaryReaderQuotas object used
when creating the XML reader. Line 243, position 38.



I have see a lot of references to this error but none of the solution seem
to help, the solutions say to update your client config, but don't say what
is the client config file, is it the web.config ?

I have created a the web.config file for the WFC service and here are the
contents, but it still does not work, also I have also updated the
maxStringContentLength in the web.config file for the web application.

Does anybody have solution to this problem?

Here's the WFC service web.config file:

Thank you

Does it happen on the Server(service) side or does the server work, but the
communication over the "wire" fail?

I would start here:
maxReceivedMessageSize="65536"

But if its something on the serverside, then pumping up the config values
won't help.
 
I would wire this up:
(This would be in the config file of your HOST.

<system.diagnostics>

<trace autoflush="true" />

<sources>

<source name="System.ServiceModel"

switchValue="Information, ActivityTracing"

<listeners>

<add name="sdt"

type="System.Diagnostics.XmlWriterTraceListener"

initializeData= "c:\wutemp\Host1.svclog" />

</listeners>

</source>

</sources>

</system.diagnostics>



(Please note the directory C:\wutemp\ has to exist.......(or whatever
directory you pick)



Then use the tool

SvcTraceViewer.exe

to look at the file

Note, on my machine, the location of the file is:

"C:\Program Files\Microsoft SDKs\Windows\v6.0\Bin\SvcTraceViewer.exe"





Likewise, you can setup the trace tool on the client side as well:


<system.diagnostics>

<trace autoflush="true" />

<sources>

<source name="System.ServiceModel"

switchValue="Information, ActivityTracing"

<listeners>

<add name="sdt"

type="System.Diagnostics.XmlWriterTraceListener"

initializeData= "c:\wutemp\Client1.svclog" />

</listeners>

</source>

</sources>

</system.diagnostics>
 
Thank you for your help, the error is comming from the Host, but the error
message is the same as what I get in my application

The formatter threw an exception while trying to deserialize the message:
Error in deserializing body of request message for operation
'GetReportFileName'. The maximum string content length quota (8192) has been
exceeded while reading XML data. This quota may be increased by changing the
MaxStringContentLength property on the XmlDictionaryReaderQuotas object used
when creating the XML reader. Line 243, position 38.

So where do I change this MaxStringContentLength, I've already changed it
in web.config and app.config but I am still getthing the error?

It looks like the basicHttpBinding config is not applied to the endpoint.
Could you try the following config to see if it works? In your original
post we can see bindingConfiguration="" so the basicHttpBinding you defined
takes no effect on the endpoint.

<endpoint address="basic" binding="basicHttpBinding"
bindingConfiguration="BasicHttpBinding_IReportService"
contract="ReportServiceLibrary.IReportService" />
