c# - System.Diagnostic.Tracing.EventSource - EventListener にイベントがない

Question

.NET 4.5 System.Diagnostic.Tracing.EventSource で問題が発生しています。完全な EventSource 実装は、この投稿の最後にあります。

この EventSource のリスナーを作成すると、イベントを受信しません。すべてのヒント、または質問をいただければ幸いです。

edit1: - Microsoft.Practices.EnterpriseLibrary.SemanticLogging.ObservableLog を試しました -> 行きません。- リスナーの EventLevel を verbose に設定します。- PerfView.exe を使用してイベントをキャプチャできます

リスナーをアクティブにする方法:

_sink = new SignalRListener();
_sink.EnableEvents(GatewayEvent.Log, EventLevel.Verbose);

私の聞き手:

internal class SignalRListener : EventListener
{
    protected override void OnEventWritten(EventWrittenEventArgs eventData)
    {
        CommandAndControlHub.SentEventEntry(eventData);

    }
}
