The way that Web API binds complex types is useful and flexible, but Web API is a little too trusting and tries to carry on to the point where the action method can be executed, even if the data that has been sent to the client can’t be used to bind to the parameters that the action method requires or if the data cannot be used within the application.

Three main problems arise when processing client data: under-posting, over-posting, and unusable data. In this chapter, I describe each in turn and explain why it presents a problem in web service development before showing you the Web API features you can use to guard ...
