JsonMaxLength exception on deserializing large json objects

Question

Intro:

Web application, ASP.NET MVC 3, a controller action that accepts an instance of POCO model class with (potentially) large field.

Mode

Answer 1

I found that the maxRequestLength did not solve the problem however. I resolved my issue with the below setting. It is cleaner than having to implement a custom ValueProviderFactory

Credit goes to the following questions:

JsonValueProviderFactory throws "request too large"

Getting "The JSON request was too large to be deserialized"

This setting obviously relates to a highly complex json model and not the actual size.
