推荐答案

如果您的应用是多线程的，并且将鼠标悬停在断点上，则会显示消息，例如自上一步以来，进程或线程已更改"，则表示此中断点不仅适用于线程创建者，还适用于一个以上的线程.按F5后，将运行另一个线程，它们将达到您的断点，这可能会使您感到困惑.为了给您某种警告，Visual Studio在下面提供了一个蓝点.因此，有时冻结其他线程以调试方法可能很有用.

If you app is multithreaded and if hovering over break point gives you message is like "The process or thread has changed since the last step" it means that this break point is applied to more then one thread, not just thread creator. After you press F5 another threads will run and they will hit your break point which can confuse you. In order to give you some kind of warning visual studio give you blue dot beneath. So sometimes it can be useful to freeze other threads in order to debug method.
