Hello again from PLANETQUANTUM.COM . :-) Below, we use Quantum, the third party .NET Jayrock JSON library, and Apple's iTunes Search API to interrogate Apple's iTunes App Store about the iOS NASA APP application. We download a JSON string from iTunes via the iTunes Search API and we use Jayrock's JsonConvert.Import method to parse the JSON string into a JSON data structure. We datamine this JSON data structure for bits of information about the iOS NASA APP application.
