コアビジネスロジックと機能を実行する、自分で作成したサービスがあります。このサービスは、1つのプロジェクトのサービスラッパーおよびWindowsライブラリプロジェクトのすべての機能として設計されています。また、Windowsライブラリプロジェクトをラップするコンソールアプリケーションもあります。
実稼働前の環境では、これは問題なく機能します。サービスが開始され、すべてが順調に進んでいます。
私たちの本番環境では、サービスを開始できません。
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()
これは変だと思い、次のようにDebug.WriteLine（）呼び出しを追加しました。
/// <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);
}
これがDbgViewキャプチャです...

BroadcastEcho()TraceLevel値に記載されているようにすべてのメッセージを表示できますが、表示されることはありDebug.WriteLine()ません。
それから、アセンブリバインディングの問題かもしれないと思いました。FusionLogの結果は次のとおりです。

どちらのマシンもWindowsServer2008R2SP1です。プリプロダクションは仮想マシンであり、プロダクションは物理マシンです。
それが何であるかについての提案はありますか？
