无法将类型为“System.__ComObject”的 COM 对象转换为接口类型“IFabricNodeContextResult2”

use*_*094 2 azure azure-service-fabric

启动有状态服务时出现以下异常,这会阻止服务完全启动。如何解决此异常并启动服务?

System.InvalidCastException HResult=0x80004002 消息=无法将类型为“System.__ComObject”的 COM 对象转换为接口类型“IFabricNodeContextResult2”。此操作失败,因为 IID 为“{472BF2E1-D617-4B5C-A91D-FABED9FF3550}”的接口的 COM 组件上的 QueryInterface 调用因以下错误而失败:不支持此类接口(来自 HRESULT 的异常:0x80004002 (E_NOINTERFACE)) . 源 = mscorlib StackTrace:在 System.StubHelpers.InterfaceMarshaler.ConvertToManaged(IntPtr pUnk, IntPtr itfMT, IntPtr classMT, Int32 标志) 在 System.Fabric.Interop.NativeRuntime.FabricEndGetNodeContext(IFabricAsyncOperationContext context) 在 SystemtimeFabricFactory.FabricRun

这是我在此服务上的 nuget 包。

尝试更新 PC 上的 Service Fabric SDK,如果您的 SDK 与您使用的 nuget 包不匹配,有时会出现奇怪的错误。

我遇到了同样的问题,并找到了这个线程。原来本地服务结构 SDK 需要更新,一旦我这样做了它又开始工作了。

服务结构 SDK 的下载链接:http : //www.microsoft.com/web/handlers/webpi.ashx? command = getinstallerredirect&appid = MicrosoftAzure-ServiceFabric- CoreSDK

(或者,如果您不喜欢单击想要安装某些内容的链接,请转到此处并找到(相同)链接:https : //docs.microsoft.com/en-us/azure/service-fabric/service-fabric - 开始)
