为什么使用 Random 和递归生成随机验证码时会产生栈溢出
我们经常会收到应用在产生验证码时崩溃的问题，查看应用程序日志会发现都是栈溢出的问题导致的崩溃。总结下来，这些不同的应用都使用了类似的代码逻辑，即使用 Random 生成随机数，然后使用递归来生成多位随机验证码。猜测这些应用的开发都参考了同一篇文章。以下是两个简单的例子，一个生成 N 位非连续重复的数字型验证码，一个生成 N 个非连续重复的字符型验证码，可以通过代码看到两个函数功能类似，逻辑也基本一致。粗略一看这个函数定义是没有问题的，但为什么会在实际使用时产生栈溢出的问题呢？

How to Solve Exception 0xC000041D
Exception 0xC000041D means that an unhandled exception was encountered during a user callback. It means that 0xC000041D is a second chance exception. So we should capture the first chance exception ,if we want to know the root cause. Usually it’s occurred in system defined callback context on Windows, for example message handling context. And customized callback will not throw the exception

Process Crash With Loading Components
代码完整性检查是系统安全中重要的功能，在 Windows 10 中加强了代码完整性的检查，譬如浏览器 Edge 中完全禁止了加载未通过微软认证的模块 Mitigating arbitrary native code execution in Microsoft Edge。但在加强代码、系统完整性检查的同时也会因为误杀导致一些问题，譬如应用程序崩溃。

Why It Show Unknown Zone Even though Adding Websites To Trust Site
If we found that properties tab show Unknown Zone(mixed), it means that some resources your website referenced belongs to other security zone. We can quickly figure out it use fiddler or F12 debugging tools. If we didn’t find any resource cross domain, we should consider whether it refer resource in ieframe.dll.

如何从 DUMP 中确认当前的 dotnet runtime 是否为调试模式
As we know for applications running in production Debug should never be set to true which will casue performance issue. The compilation of ASP.NET pages takes longer (since some batch optimizations are disabled) Code can execute slower (since some additional debug paths are enabled) Much more memory is used within the application at runtime Scripts and images downloaded from the WebResources.axd handler are not cached ASP.NET Timeouts
