C# 找不到使用单类型Web服务的ASMX

我试图在CentOS服务器上使用Apache中的mono和mod_mono启动一个ASMX Web服务，但我收到一个500错误，表示找不到webservice类型

我在Ubuntu环境中也尝试过这个，但我得到了同样的错误。我尝试卸载mono、apache并重新安装了几次，我配置了mod_mono，但我似乎不知道是什么原因导致了这种情况

下面是整个错误消息

谢谢您的帮助。

您使用的是哪个版本的mono？最新版本是随yum一起安装的，谢谢您的帮助。yum安装的是哪个版本？您可以通过在控制台中写入以下内容进行检查：mono-versionit输出：mono JIT编译器版本2.10.8 tarball Wed Dec 4 09:32:19 EST 2013alright，这是一个非常旧的mono版本，您需要升级
