Я пытаюсь создать расширение Visual Studio 2022 для обнаружения всякий раз, когда нависает определенная строка в файле .cpp или .h, в банкомате проекта есть только два файла .
Я установил точку останова на InitializeAsync файла ImagePackage.cs, когда я начинаю отладку расширения, оно попадает и печатает:
"Компоненты MEF инициализированы успешно ."
Я также установил точки останова для всех функций Image.cs, но никто не пострадал.
Я пропустил что-нибудь где-нибудь, чтобы работало обнаружение наведения?
