自Windows 10 1709更新以来-System.OutOfMemoryException c＃.net

Question

我的winforms应用程序一直运行良好，直到最新的Windows 10 1709更新为止，此后更新运行我的应用程序在运行独立的.exe或Visual Studio 2017时不断崩溃。该应用程序在具有最新1709更新的任何计算机上崩溃。 作为测试，我创建了一台Windows 7计算机，并且可以完美运行，并且Windows 10 1709之前的所有版本都可以正常运行。

当我得到System.OutOfMemoryException异常时，它是相当随机的；但是通常在System.Form.Timer触发或运行线程时（这可能是一个提示！）。

可以肯定的是，我没有记忆力不足！ （32GB，其中50％可用在我的开发机器上）。

我很茫然是什么原因造成的，并尝试了以下方法：

该解决方案包含大约30个C＃项目。 -我已从.Net 4.6更新到4.6.1，然后又更新到4.7和4.7.1-更新了所有Nuget项目。 -在Windows 7上编译的代码在Windows 10上运行（崩溃）-在Windows 7上运行良好。-在Windows 10 Home，Windows 10 Pro（1709）上运行。 在较旧的Windows 10上运行良好！ -全新安装具有32GB RAM的Windows 10 Pro（我的开发机）。 -禁用计时器和线程（仅在其他位置获得异常）。

回滚OS并不是一个解决方案，因为我的用户依赖运行Windows 10的该软件。上周，我一直在寻找此解决方案，但没有解决方案，希望我能得到一些好的指导以最终解决此问题。

以下是两个回溯-自从我更新到最新的1709以来，我有100个此类回溯（通过rollbar.com）：

Answer 1

原来实际的问题是.Net WebBrowser控件，这导致使用大量内存。.我同时打开了许多Fice WebBrowser控件..会吃掉2GB的RAM！ （如果x32编译的应用程序没有崩溃，则x64的使用时间会更长！）。

删除它们，应用程序仅再次消耗25MB！

ps切换到CefSharp，看看效果是否更好！
