devenv.exe 调试后崩溃

Question

当我在调试停止后尝试编辑源代码时，我的 Visual Studio 2015（带有 update3）崩溃了。 （它也发生在 C# WinForm、WPF 和控制台项目上）
一个月前还好……

我收到了 System.AccessViolationException 崩溃。
而且我在调试的时候发现了一些奇怪的东西：

• 无法在我的程序中获取任何变量，即使在即时窗口中也是如此
• 但我仍然可以获得其他信息（如线程、堆栈...）
• 诊断工具不起作用
• 停止调试后，.vshost.exe 仍然存在

我已经修复了Visual Studio，但错误仍然发生。

Answer 1

就像 Hans Passant 的建议一样，至少，在 TOOLS->Options->Debugging 下禁用“Edit and Continue”功能后，您已经解决了 VS 崩溃的问题。

另外，如果看不到局部变量，请检查是否与调试选项“使用托管兼容模式”和“使用原生兼容模式”有关。
