enterprise-library-6 - Enterprise Library 6.0 参数不能为空

Question

我在 global.asax 文件中设置了如下所述的异常管理器

protected void Application_Start(object sender, EventArgs e)
        {
            IConfigurationSource source = ConfigurationSourceFactory.Create();
            DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory(source));

            var logwriterFactory = new LogWriterFactory(source);
            var logWriter = logwriterFactory.Create();
            Logger.SetLogWriter(logWriter);

            var exceptionPolicyFactory = new ExceptionPolicyFactory(source);
            var exceptionManager = exceptionPolicyFactory.CreateManager();
            ExceptionPolicy.SetExceptionManager(exceptionManager);

但是当我使用企业库 6.0 异常处理时我仍然面临这个问题

请帮我解决这个问题
