Question

我在 sharepoint 有一个提供商托管的应用程序，可以在本地正常运行。我按照本教程将其发布到azure

http://blogs.technet.com/b/sharepointdevelopersupport/archive/2013/09/05/how-to-deploy-a-provider-hosted-app-as-an-azure-site.aspx

但是，发布网络服务后不起作用，我收到此异常:

[InvalidOperationException: The type 'x.IntranetWeb.Services.AppEventReceiver', provided as the Service attribute value in the ServiceHost directive, or provided in the configuration element system.serviceModel/serviceHostingEnvironment/serviceActivations could not be found.]

我没有碰过的 web.config。

以及远程事件接收器的一段代码

<%@ ServiceHost Language="C#" Debug="true" Service="x.IntranetWeb.Services.AppEventReceiver" CodeBehind="AppEventReceiver.svc.cs" %>


namespace x.IntranetWeb.Services
{
    public class AppEventReceiver : IRemoteEventService
    {

还有global.asax，因为这是一个带有.svc的MVC应用程序，也许它与路由有关？

public class MvcApplication : System.Web.HttpApplication
    {
        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }
    }

1. 检查您的服务类名称，它应该与 *.svc 标记文件“Service = ...”中的名称相同

例如:

namespace my{

     public class DummyService: IWebService
     {
        //implementation
     }
}

*.svc 标记:<%@ ServiceHost Language="C#"Debug="true"Service="my.DummyService"CodeBehind="myservice.svc.cs"%>

尝试检查一下: WCF Web Service not working after IIS restart

“有趣的是，预编译 Web 服务时会引发上述错误。我尝试定期运行该服务(无需预编译)，但该问题不再出现。

我在 Web 服务中使用了一个库，因此实际上 Web 服务本身根本没有任何代码。也许这就是原因。无论如何，由于没有代码，所以不预编译也可以”

您可以检查您的服务的应用程序池吗？开始了吗？
