在Service Fabric中调试.NET Core RC2 Web应用程序时出现错误消息

Question

我终于设法将.NET Core RC2 Web应用程序上传到Service Fabric。但是一旦部署，我在Visual Studio中收到以下错误消息：

在Service Fabric Explorer中，我在Web应用程序的分区中收到以下错误：

我的ServiceManifest.xml如下所示：

<?xml version="1.0" encoding="utf-8"?>
<ServiceManifest Name="WebApplicationPkg"
             Version="1.0.0"
             xmlns="http://schemas.microsoft.com/2011/01/fabric"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <ServiceTypes>
    <StatelessServiceType ServiceTypeName="WebApplicationType" />
  </ServiceTypes>

  <CodePackage Name="Code" Version="1.0.0">
    <EntryPoint>
      <ExeHost>
        <Program>WebApplication.exe</Program>
      </ExeHost>
    </EntryPoint>
  </CodePackage>
  <ConfigPackage Name="Config" Version="1.0.0" />

  <Resources>
    <Endpoints>
      <Endpoint Name="ServiceEndpoint" />
    </Endpoints>
  </Resources>
</ServiceManifest>

我的project.json：

      "web.config"
    ]
  },

  "scripts": {
    "prepublish": [ "npm install", "bower install", "gulp clean", "gulp min" ],
  }
}

我的Progam.cs：

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseStartup<Startup>()
            .Build();

        host.Run();
    }
}

谁能看到我做错了什么？这个错误来自哪里？ 当我在本地运行应用程序时，它很好。只要我将其部署到Service Fabric，我就会遇到这些错误。

谢谢！

我之前遇到过类似的问题。我还没找到特定的问题。我怀疑这是因为服务没有将自身注册到服务结构运行时，导致健康分区（针对特定服务）的数量低于指定值（应用程序清单中的InstanceCount）。

我通过基于SDK中提供的OwinCommunicationListener创建通信侦听器来解决它。我的实现与Hosting repo by weidazhao (David)中的实现非常相似。我建议，因为它似乎足够接近官方SDK中的内容。
