我完成了此处找到的安装文档。我有一个示例仪表板应用程序和一个示例客户端应用程序，它们将 Elmah 错误抛出到 SQL 数据库中。
客户端应用程序的 elmah 工作正常，我可以在 elmah.axd 查看错误日志。当我尝试访问仪表板应用程序时，页面加载并启动“发送命令”消息。然后我从第一个“send?transport=...”命令中得到 500 Internal Server 错误。
Dashboard 应用程序是在我的本地主机上运行的 ASP.Net MVC 5 应用程序。
这是生成错误的 URL：
http://localhost/ElmahR/elmahr/commands/send?transport=serverSentEvents&connectionToken=k6HUNtFtmSXrJZgH_2oexTg_cx-el2G7PhJ6NZD4aBLT_svpboE31meZG4wazu7VDS8_WWRjnnV-yGSVhBzBbYWlXFTo08onRvNCzYgYhH5kwMw9KvKOSQIakT6Wzv_Y0
当我检查该错误时，这就是我得到的：

知道什么可能配置不正确以引发此错误吗？我需要用 Razor 改变什么吗？
这就是我所看到的：
