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

我只是重新装填，清理和重建我的作品。

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。

我之前一直在摆弄我的csproj文件。所以在项目属性(VS 2013) > Web选项卡>服务器部分>[下拉]，我有“IIS快速”选择当我以前有“本地IIS”选择。一旦我将设置修正为之前的设置，断点就可以工作了。

至:

Tools > Options > Debugging > General > unchecked "要求源 文件与原始版本完全匹配”

在我的案例中，问题在于ASP。在项目属性>>Web下未启用NET调试
