启动有状态服务时出现以下异常，导致服务无法完全启动。如何解决此异常并启动服务？
System.InvalidCastException HResult=0x80004002 Message=Unable to cast COM object of type 'System.__ComObject' to interface type 'IFabricNodeContextResult2'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{472BF2E1-D617-4B5C-A91D-FABED9FF3550}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

这是我在该服务上拥有的 nuget 软件包。
<?xml version="1.0" encoding="utf-8"?>

这是代码
namespace PrintFileStatefulService
{

/// An instance of this class is created for each service replica by the Service Fabric runtime.
/// </summary>
internal sealed class PrintFileStatefulService : StatefulService, IPrintFileService
{
public PrintFileStatefulService(StatefulServiceContext context)
: base(context)
{ }
public Task GeneratePrintFile(Guid duesbillingId)
{
throw new NotImplementedException();
}
/// <summary>
/// Optional override to create listeners (e.g., HTTP, Service Remoting, WCF, etc.) for this service replica to handle client or user requests.
/// </summary>

/// <returns>A collection of listeners.</returns>
protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
{
//return new ServiceReplicaListener[0];
return new[]
{
new ServiceReplicaListener(context => this.CreateServiceRemotingListener(context))
};
}
}
}
最佳答案
我遇到了同样的问题，并发现this thread 。事实证明本地服务结构 SDK 需要更新，一旦我更新它就重新开始工作。
