服务结构上托管的ASP.Net核心项目无法启动

Question

我们尝试在Service Fabric上托管一个ASP.Net核心MVC RC1 DNX项目。部署工作正常，但项目尚未启动。根据我们的日志，似乎服务结构无法找到启动类并创建实例。我们下载了一个可以正常运行的演示项目，但无法启动并运行我们的项目。我们看不到任何有用的日志信息。不在事件日志，服务结构日志流或Visual Studio调试提示中。我们可以做些什么来启用更多调试信息。我们的配置或项目设置可能出什么问题？这是我们项目的关键部分:

Answer 1

我建议在GitHub上探索这个例子。

此示例演示如何在无状态/有状态服务的通信监听器中使用ASP.NET Core。

此示例已更新为使用dotnet cli。

有2个不同的分支dnx和dotnetcli。 dnx分支可以在Visual Studio中使用。
