Resolved ASP.Net MVC Error- The JSON request was too large to be deserialized

Sometimes we get the below error while trying to post large data over MVC action -

The JSON request was too large to be deserialized
System.InvalidOperationException: The JSON request was too large to be deserialized.

This error comes because default limit for JSON deserializer members exceeds. To resolve this error we need to increase the size for MaxJsonDeserializerMembers.

One can increase the json limit by adding following settings to appSettings section on web.config file.

<add key="aspnet:MaxJsonDeserializerMembers" value="150000" />
