asp.net - 在 Mono 中配置 System.Net 的问题

Question

我试图在我的 Mono 项目的 Web.config 中配置 System.net 节点。

我不断收到此异常:

System.Configuration.ConfigurationErrorsException
Error deserializing configuration section defaultProxy: Unrecognized attribute 'enabled'. (/usr/share/nginx/aspnet/Web.config line 1)

Description: HTTP 500.Error processing request.
Details: Non-web exception. Exception origin (name of application or object): System.Configuration.

我不知道如何让我的应用程序接受启用属性设置为 true 的 defaultProxy 节点或使用其他一些设置。

如果我从 Web.config 中删除 System.net 节点，则使用 WebClient 的应用程序部分将超时。

我相信您已经在单声道中发现了一个错误。 DefaultProxySection constructor seems to forget to add the attribute properties to the collection ，所以配置阅读器不知道它们。

请注意，enabled 的默认值属性是 true因此您可以省略该设置作为解决问题的方法。

尽管如此，请报告 bugzilla.xamarin.com 中的错误
