我有一个我编写的服务，它执行核心业务逻辑和功能。该服务被设计为一个项目中的服务包装器以及 Windows 库项目中的所有功能。我也有包含 Windows 库项目的控制台应用程序。
在我们的预生产环境中，这工作得很好。服务开始，一切都在其愉快的小路上进行。
在我们的生产环境中，服务无法启动。
Application: URTWorkerService.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.IO.FileNotFoundException
Stack:
at URTWorker.Worker.Run()
at System.Threading.ThreadHelper.ThreadStart_Context(System.Object)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object, Boolean)
at System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
at System.Threading.ThreadHelper.ThreadStart()
我认为这很奇怪，并像这样添加了一个 Debug.WriteLine() 调用：
/// <summary>
/// Entry point method into the Worker class
/// </summary>
public void Run()
{
Debug.WriteLine("Did we make it this far?");
var exitEventArgs = ExitEventArgs.Clear;
try
{
BroadcastEcho("Worker::Run::Enter", TraceLevel.Verbose);
WorkerStartedOn = DateTime.Now;
State = AsyncState.Running;
BroadcastEcho("Worker::Run::Pre initialize", TraceLevel.Verbose);
Initialize();
BroadcastEcho("Worker::Run::Post initialize", TraceLevel.Verbose);
ExecuteWorkerLoop();
}
catch (Exception ex)
{
exitEventArgs.Reason = ExitReason.Exception;
var vars = new Dictionary<string, string>();
StandardMessage message;
// TODO Comment about this
if (ex is FormatException && ex.Message.Contains("FieldNames.cs"))
{
BroadcastEcho("The field definition has changed. Generating new code file.", ex);
var path = CreateConstantsCodeFile();
BroadcastEcho("The file has been saved to " + path, TraceLevel.Error);
vars.Add("FieldsNamesPath", path);
message = StandardMessage.NewFieldsNameFile;
}
else
{
BroadcastEcho("An unhandled exception was thrown", ex);
vars.Add("ExtraInfo", "<b>This is a crashing exception.</b>");
message = StandardMessage.UnhandledError;
}
Notifier.SendErrorMail(message, vars, ex);
}
var lastCount = -1;
while (Notifier.MailInTransit.Count > 0)
{
if (lastCount != Notifier.MailInTransit.Count)
{
var suffix = (
lastCount != 1
? "s"
: string.Empty);
lastCount = Notifier.MailInTransit.Count;
BroadcastEcho(string.Format("Waiting for {0} mail item{1} to finish sending", lastCount, suffix), TraceLevel.Info);
}
Thread.Sleep(0);
}
State = AsyncState.Stopped;
BroadcastEcho("Worker::Run::Exit", TraceLevel.Verbose);
Exit(exitEventArgs);
}
这是 DbgView 捕获...

您可以看到所有BroadcastEcho()消息，如 TraceLevel 值所述，但Debug.WriteLine()从未出现。
然后我认为这可能是程序集绑定的问题。这是融合日志的结果：

两台机器都是 Windows Server 2008 R2 SP1。预生产是虚拟机，生产是物理机。
关于它可能是什么的任何建议？
