The maximum string content length quota (8192) has been exceeded while reading XML data

Hello,

I'm in trouble with wcf hosted on Windows Azure as a web service. This error occurs when I send a lot of string (>10kb) to the service.

Error message:

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

I tried to re-configure the config.dll.client to increase the readerQuotas but it wont work:

<readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647"
            maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />

Please help me
