我有一个由 ASP .Net 网站调用的 WCF Web 服务。在我的 web 方法中，我故意不捕获异常，因为我希望它们由客户端网站处理。Web 服务纯粹是一个内部应用程序，我希望它表现得像一个标准库，期望调用者处理异常。我在服务 web.config 中有 includeExceptionDetailInFaults="true"。当我的服务引发异常时，我收到此错误：

Log Name:      Application

如何解决这个问题，以便我的客户能够捕获服务抛出的异常？

我找到了问题的原因 - 在我的 Web 服务中的工作线程 (System.Threading.ThreadPool.QueueUserWorkItem) 中引发了异常，因此当然没有得到处理。通过添加异常处理程序并将日志记录到工作线程来修复。
