I suffered from this recently, and in my case I traced the problem back to something I was doing when testing: changing the system time. I'm not suggesting this is the case for everyone, but thought I'd mention it since it hasn't been mentioned already. It appears if you start moving the clock around between debug builds then it can get very confused about what order various files have been created it - I can only assume it is using file modified dates to determine if the source code is valid or not, and which binaries it needs to recompile.

这也是一个重新保存网页的选项。配置以碰撞其修改时间。

VS 2017的一些版本(结合。editorconfig)也有一个问题:从15.3开始，当文件的字符集与.editorconfig (utf8或utf8-bom)中的字符集不一致时，断点就不起作用了。

对于一个类似的问题，我做了如下处理:

取消选中Debug -> option -> General菜单中的“Enable Just My Code”选项

确保在csproj中将<Optimize>false</Optimize>设置为false

在我的例子中，其他建议都不起作用，但是重新克隆我的存储库使这个问题消失了。

对我来说，没有一个项目能解决这个问题。我只是在函数中添加了一行新代码，类似于:

int a=0;

通过添加这个，我想我触发了visual studio在原始版本中添加这个功能
