C# WPF как передать данные из потока на форму?

Question

Метод install_uninstall выполняется в потоке. В нем вызывается другой метод retVal_install (список ответов установки). Необходимо передать данные из retVal_install на форму для отображения хода установки в реальном времени. Подскажите как это сделать?
