In nearly all my previous projects I've worked on required some kind of manipulation with reading some form of JSON data.
To allow better integration into my application, I always create strongly-typed classes that mirror the structure of the incoming data feed. This in turn allows me to serialize the JSON and select specific properties I require. But sometimes, its quite difficult and confusing to the exact class structure right, especially when the JSON contains lots of fields of data.
When I find this is the case, I use json2csharp.com. By simply pasting the contents of your JSON, the site does all the hard work and creates all the strongly-typed classes for you.
