但是,如果我将页面添加到URL中,则会出现：@H_404_3@

一个SO answer建议删除所有默认文档(在IIS中),除了真正的文档.我试过了(下面的图片),但没有帮助.@H_404_3@

为什么IIS在使用根URL(http：// localhost / SignalRChat)时不会提供该页面？@H_404_3@

删除默认文档后,这是web.config的相关部分：@H_404_3@

<defaultDocument>
    <files>
        <remove value="default.aspx" />
        <remove value="iisstart.htm" />
        <remove value="index.html" />
        <remove value="index.htm" />
        <remove value="Default.asp" />
        <remove value="Default.htm" />
        <add value="ChatPage.cshtml" />
    </files>
</defaultDocument>

这是处理程序部分：@H_404_3@
