c # — переполнение или переполнение в арифметической операции wpf

Переполнение или переполнение в арифметической операции wpf

Попытка воссоздать пример virdiSDK в WPF с использованием MVVM + Prism

Сервер терминалов приступил к работе, но когда я пытаюсь закрыть приложение или получить фокус на текстовое поле для ввода, я получаю сообщение об ошибке переполнения или недостаточного значения в арифметической операции

Иногда источник: windowsbase
Несколько раз это так: PresentationFramework
