Error Serializing String in WebService call


This morning I ran into an issue with returning back a text string as result from a Web Service call. the Error I was getting is below

************** Exception Text **************
System.ServiceModel.CommunicationException: Error in deserializing body of reply message for operation 'GetFilingTreeXML'. ---> System.InvalidOperationException: There is an error in XML document (1, 9201). ---> System.Xml.XmlException: 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 9201.

I did a search and the results are below: Search Results

Most of those are WCF related but were enough to point me in the right direction. I will post answer as reply.
