The formatter threw an exception ....The maximum string content length quota (8192) has been exceeded while reading XML data

Question

Whenever I try to save the xmlString as a text file through server using wcf Service, I keep getting the following error:

The formatter threw an exception while trying to deserialize the message: Error in deserializing body of request message for operation 'saveAnnotations'. 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 1, position 21897.

I get this exception whenever I try to save the xmlstring by calling the wcf service.

Below are my WebConfig (Client Configuration settings) and AppConfig (Server Configuration settings):
