如何修复“System.ServiceModel.ExceptionDetail”未标记为可序列化

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，我希望它的行为类似于期望调用者处理异常的标准库。我在服务 web.config 中包含 ExceptionDetailInFaults="true"。当我的服务引发异常时，我收到此错误：

Log Name:      Application

如何解决此问题，以便我的客户端能够捕获服务引发的异常？

如何修复“System.ServiceModel.ExceptionDetail”未标记为可序列化

我找到了问题的原因 - 异常在我的 Web 服务中的工作线程（System.Threading.ThreadPool.QueueUserWorkItem）中抛出，所以当然没有被处理。通过添加异常处理程序并将日志记录到工作线程进行修复。
