我在这方面没有发现太多,花了一天的大部分时间后...我正在寻求帮助。
我得到的例外是:
无法将类型为'System .__ ComObject'的COM对象转换为接口 键入“ IFabricSecretStoreClient”。该操作失败,因为 IID接口的COM组件上的QueryInterface调用 “ {38C4C723-3815-49D8-BDF2-68BFB536B8C9}”由于以下原因而失败 错误:不支持此类接口(HRESULT的异常:0x80004002 (E_NOINTERFACE)。
我可以使用以下代码实例化有状态服务的代理:
var servicekey = new ServicePartitionKey(0);
var queryserviceUri = new Uri("fabric:/XXXX/xxxxxxxxxx");
var proxyHandle = ServiceProxy.Create<IAnInterfaceName>(queryserviceUri, servicekey, TargetReplicaSelector.PrimaryReplica);
然后我使用代理服务器:
var result = await proxyHandle.OperationOnServiceContract(dataPackage);
这时我得到了错误...

哦,我正在用它作为听众:
protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
{
return this.CreateServiceRemotingReplicaListeners();
}
答案 0 :(得分:3)
关于这些问题的说明:
每当您使用针对较旧版本的Service Fabric运行时的更新的Nuget包时,就会发生这些COM问题,就会发生这种错误。
您应该始终使用针对相同集群运行时版本的软件包,在最后一种情况下,请使用早于集群版本的软件包。
