Visual Studio 2015原生C++；单元测试启动 当我为本地C++运行简单的单元测试时，在测试框架在单元测试的第一行上遇到断点之前，我会收到许多异常。例外情况如下所示。 如何关闭它们或如何修复它们？

我还看到调试器中的每一步都要花费大量的时间，就像在远程机器上调试一样本机单元测试正常吗？

更新1:

它确实是从clr调用的，正如下面所示的调用堆栈信息（所以在到达单元测试的第一行之前一定要这样）

---

EEFileLoadException是由.NET CLR引发的异常。如果没有堆栈跟踪，就无法猜测它们是来自单元测试运行程序还是您的代码。“很多类似的行”并没有给出很高的可能性，即是单元测试运行人员行为不端。强制调试器在异常时停止，以便查看更多信息：调试>窗口>异常设置>勾选“C++异常”框。如果这指向您的代码，则将调试器类型设置为“mixed”，以便您可以看到托管异常。我更新了调用堆栈信息，但正如前面提到的，它发生在到达单元测试的第一行之前…：）您没有启用符号服务器，因此我们仍然不知道任何情况。我不太确定你能用调试器到达那里。向另一个团队成员寻求帮助，让他运行相同的单元测试。如果它没有在他的机器上重新存储，那么您就知道这是一个不稳定的机器问题。我启用了symbol server-这是VS能够显示的内容尝试选择全部（单击列表，然后单击
