Я пытаюсь десериализации строку с помощью библиотеки DLL Newtonsoft.Json из RunTime Version v2.0.50727Почему JSON DeSerialization терпит неудачу в C#?
Версия 4.5.0.0.
Target FrameWork .Net Framework 2.0
Для строки:

Ваш JSON-букварий выглядит как ошибка 404. Вы уверены, что запрашиваете правильный URL? – Ivancho
Не могли бы вы показать нам класс ExecutionReportEntry? Строка представляется действительной JSON, поэтому, возможно, существует несоответствие между классом и JSON –
. Я добавил больше JSON в более читаемом формате. –
