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

Question

我的winforms應用程序一直運行良好，直到最新的Windows 10 1709更新為止，此后更新運行我的應用程序在運行獨立的.exe或Visual Studio 2017時不斷崩潰。該應用程序在具有最新1709更新的任何計算機上崩潰。 作為測試，我創建了一台Windows 7計算機，並且可以完美運行，並且Windows 10 1709之前的所有版本都可以正常運行。

當我得到System.OutOfMemoryException異常時，它是相當隨機的；但是通常在System.Form.Timer觸發或運行線程時（這可能是一個提示！）。

可以肯定的是，我沒有記憶力不足！ （32GB，其中50％可用在我的開發機器上）。

我很茫然是什么原因造成的，並嘗試了以下方法：

該解決方案包含大約30個C＃項目。 -我已從.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項目。 -在Windows 7上編譯的代碼在Windows 10上運行（崩潰）-在Windows 7上運行良好。-在Windows 10 Home，Windows 10 Pro（1709）上運行。 在較舊的Windows 10上運行良好！ -全新安裝具有32GB RAM的Windows 10 Pro（我的開發機）。 -禁用計時器和線程（僅在其他位置獲得異常）。

回滾OS並不是一個解決方案，因為我的用戶依賴運行Windows 10的該軟件。上周，我一直在尋找此解決方案，但沒有解決方案，希望我能得到一些好的指導以最終解決此問題。

以下是兩個回溯-自從我更新到最新的1709以來，我有100個此類回溯（通過rollbar.com）：

Answer 1

原來實際的問題是.Net WebBrowser控件，這導致使用大量內存。.我同時打開了許多Fice WebBrowser控件..會吃掉2GB的RAM！ （如果x32編譯的應用程序沒有崩潰，則x64的使用時間會更長！）。

刪除它們，應用程序僅再次消耗25MB！

ps切換到CefSharp，看看效果是否更好！
