devenv.exe调试后崩溃
devenv.exe crash after debugging
当我尝试在调试停止后编辑源代码时，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......
我得到了一个 System.AccessViolationException 的崩溃。
而且我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，即使是在立即 window
- 但我仍然可以获得其他信息（如线程、堆栈...）
- 诊断工具不工作
- 停止调试后，
.vshost.exe 仍然存在
我已经修复了Visual Studio，但是还是报错
操作系统：Windows7x64

像 Hans Passant 的建议一样，至少，您在 TOOLS->Options->Debugging 下禁用 "Edit and Continue" 功能后解决了 VS 崩溃问题。
另外，如果看不到局部变量，请检查是否与调试选项"Use Managed Compatibility Mode"和"Use Native Compatibility Mode"有关。
当我尝试在调试停止后编辑源代码时，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......

- 停止调试后，

像 Hans Passant 的建议一样，至少，您在 TOOLS->Options->Debugging 下禁用 "Edit and Continue" 功能后解决了 VS 崩溃问题。
另外，如果看不到局部变量，请检查是否与调试选项"Use Managed Compatibility Mode"和"Use Native Compatibility Mode"有关。
