How can I bypass the maximum nametable character count quota (16384) with my custom binding?

Question

I am recieving the below CommunicationException from a WCF service call. I understand that according to this answer, I need to set the TextMessageEncodingBindingElement.ReaderQuotas object, but it appears to be read only (though in the documentation it say it is Get/Set).

Does anyone know how to do this in code?

You can't set the ReaderQuotas object, but you can set individual properties on it, like so:

textMsgEncoder.ReaderQuotas.MaxNameTableCharCount = 2147483647 or other appropriate value
