我有一个.NET x64 .NET 4巨大的应用程序。那个app使用不同的其他模块。应用程序挂起（显示“未响应”标题）。我有完整的资源（例如3d party，NHibernate除外）。但是，由于在附加Managed和Native支持期间“64位调试操作花费的时间超出预期”，我无法使用Visual Studio 2012。如果我只在托管模式下使用附加都很好，但是没有断点（“Debug-＆gt; break”不起作用）。所以我看不到调用堆栈，了解问题。
我使用Process Explorer完全转储了我的应用程序，并开始使用WinDbg x64来处理它。

感谢DebugDiag我发现了一个问题（看起来像是一个问题）
GC正在此过程中运行。触发GC的线程是27。
应用程序的以下主题（0 16 18 22 23 30 32 35 36 37 39 40 41 44 46 48 49 50）正在等待.net垃圾回收完成。线程27触发了垃圾收集。
以下应用程序的线程正在等待进入.NET Lock（24 25 26 28 29 31 33 34 38 42 43 45 47）查看线程37的callstack以查看为什么该线程id在等待以及为什么它是没有释放锁。
在线程27拥有的0x0023fef0处检测到可能阻塞或泄漏的关键部分
以下应用程序线程正在System.Threading.Monitor.Wait（17 19 20 21）中等待
以下应用程序线程正在等待WaitOne（15）
线程27：http://pastebin.com/GS0r8hi7
我尝试使用SOSEx！dlk命令，发现没有死锁。 我接下来需要做什么？
