Question

我在使用wsHtpBinding帮助页面创建wcf服务时出错是收到错误而服务也无法正常工作

帮助页面错误：

无法找到资源。说明：HTTP 404.您要查找的资源（或其中一个依赖项）可能已被删除，名称已更改或暂时不可用。请查看以下网址，确保拼写正确。 http://localhost:80/Service1.svc/help

我的老工作wsHttpbinding项目web.config但它现在不能正常工作：

在我的情况下，我发现在IIS /网站上安装了一个Microsoft IIS过滤模块Url Scan 3.1，它有自己的限制来根据内容大小拒绝传入请求并返回＆＃34 ; 404未找到页面＆＃34;。

通过将%windir%\System32\inetsrv\urlscan\UrlScan.ini设置为所需的值，可以在MaxAllowedContentLength文件中更新该限制。

例如。以下将允许最多300 MB的请求

MaxAllowedContentLength = 314572800
