部署的WCF Silverlight应用程序返回404错误

Question

我有一个托管在IIS 8中的Silverlight 5 Web应用程序。我可以在VS 2013中很好地运行我的应用程序，但是在部署到运行IIS 8的Windows 2012服务器时，我的应用程序无法运行。 Fiddler为我提供了以下内容：说明：HTTP404。您正在寻找的资源（或其依赖项之一）可能已被删除，名称更改或暂时不可用。 请查看以下网址，并确保其拼写正确。

我的Web.config文件如下所示：

 <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <sectionGroup name="system.serviceModel"> <section name="domainServices" type="System.ServiceModel.DomainServices.Hosting.DomainServicesSection, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" allowDefinition="MachineToApplication" requirePermission="false" /> </sectionGroup> </configSections> <appSettings> <add key="ApplicationName" value="......" /> </appSettings> <system.web> <httpModules> <add name="DomainServiceModule" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </httpModules> <httpRuntime targetFramework="4.5" maxRequestLength="10000000" executionTimeout="120" /> <compilation debug="true" targetFramework="4.5"> <assemblies> <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> </assemblies> </compilation> <roleManager enabled="true" /> <authentication mode="Forms"> <forms name=".ABCD_ASPXAUTH" timeout="20" /> </authentication> <profile> <properties> <add name="FriendlyName" /> </properties> </profile> <pages controlRenderingCompatibilityVersion="4.0" /> <customErrors mode="RemoteOnly" defaultRedirect="DefaultRedirectErrorPage.aspx"> <error statusCode="403" redirect="AccessDenied.htm" /> <error statusCode="404" redirect="Http404ErrorPage.aspx" /> </customErrors> </system.web> <system.web.extensions> <scripting> <webServices> <authenticationService enabled="true" requireSSL="false" /> <roleService enabled="true" /> </webServices> </scripting> </system.web.extensions> <system.webServer> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <add name="DomainServiceModule" preCondition="managedHandler" type="System.ServiceModel.DomainServices.Hosting.DomainServiceHttpModule, System.ServiceModel.DomainServices.Hosting, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31BF3765AD364E35" /> </modules> </system.webServer> <system.serviceModel> <client /> <behaviors> <serviceBehaviors> <behavior name="AppServicesBehavior"> <serviceMetadata httpGetEnabled="true" /> </behavior> <behavior name="ReportServiceBehavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebBehavior"> <webHttp /> </behavior> </endpointBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="userHttp"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <services> <service name="System.Web.ApplicationServices.AuthenticationService" behaviorConfiguration="AppServicesBehavior"> <endpoint contract="System.Web.ApplicationServices.AuthenticationService" binding="basicHttpBinding" bindingConfiguration="userHttp" bindingNamespace="http://asp.net/ApplicationServices/v200" /> </service> <service name="System.Web.ApplicationServices.RoleService" behaviorConfiguration="AppServicesBehavior"> <endpoint contract="System.Web.ApplicationServices.RoleService" binding="basicHttpBinding" bindingConfiguration="userHttp" bindingNamespace="http://asp.net/ApplicationServices/v200" /> </service> <service name="Telerik.Reporting.Service.ReportService" behaviorConfiguration="ReportServiceBehavior"> <endpoint address="" binding="basicHttpBinding" contract="Telerik.Reporting.Service.IReportService"> <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="resources" binding="webHttpBinding" behaviorConfiguration="WebBehavior" contract="Telerik.Reporting.Service.IResourceService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> </service> </services> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel> <connectionStrings> '''''''''''''''' </connectionStrings> <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Critical, Error, Warning" propagateActivity="true"> <listeners> <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="C:\\Projects\\Log\\Traces.svclog" /> </listeners> </source> </sources> </system.diagnostics> </configuration> 

有人可以告诉我为什么仍然可以从VS 2013运行时，以前配置的Win 2012服务器为什么现在不加载已部署的应用程序吗？ 还是有办法让Fiddler给出更详细的错误？

我将“跟踪”设置为“开”，但是日志没有提供任何更好的线索。

谢谢。

Answer 1

您可能在开发计算机上安装了RIA Services，但未在服务器上安装它。

您有两种选择：

1. 切记在要部署到的每台服务器上安装RIA Services

2. 将RIAServices.Server NuGet包添加到* .Web项目。 这会将RIAServices dll的私有本地副本添加到您的解决方案中。
