C# 进程有时无法运行主方法中的任何内容，并卸载应用程序域

我有两个C#应用程序，用户界面运行在Mono 4.0.3和OpenSUSE 13.1上。第一个应用程序启动第二个应用程序，然后等待它退出。有时（10次中有1次）第二个应用程序无法加载-进程将启动，但占用0%的处理器时间。如果我将Console.WriteLine放在Main方法的最开头，那么WriteLine永远不会发生

我启动流程非常简单：

var psi = new ProcessStartInfo("mono", " --gc=boehm MyProgram.exe");
psi.RedirectStandardOutput = true;
psi.RedirectStandardError = true;
psi.UseShellExecute = false;
var process = Process.Start(psi);

按照的步骤，gdb的mono_回溯输出为：

我在针对mono 4.0.3的测试自动化（包括nunit和我自己的流程）中看到挂起和一些错误，3.12.1中的挂起和错误在升级到mono 4.0.4.1后得到了解决

---

我在4.0.4的发行说明中没有看到任何与此直接相关的内容。但肯定解决了我遇到的这些问题。

您提供的堆栈跟踪本身毫无意义。您需要显示

线程apply all where

的输出，谢谢，我已经添加了输出。
