Правильный способ как зарегистрировать пользовательский IStateSerializer <T>

Question

Где именно должна происходить регистрация пользовательского IStateSerializer в течение срока службы StatefulService, чтобы быть эффективной?

internal sealed class Automat : StatefulService
{
    public Automat(StatefulServiceContext context)
        : base(context)
    { }

    protected override async Task RunAsync(CancellationToken cancellationToken)
    {
        var ok = this.StateManager.TryAddStateSerializer(new DeviceStateSerializer());
        if (!ok)
        {
            Log.FailedToRegisterStateSerializer();
            throw new Exception("Failed to register state serializer.");
        }

        ...
    }
}

public sealed class DeviceStateSerializer : IStateSerializer<DeviceState>
{ ... }

Вскоре после развертывания событие работоспособности Раздел находится в потере кворума.(System.FM) сообщается, и в дальнейшем второстепенные экземпляры службы с сохранением состояния будут выдавать предупреждения:

Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. Alternatively, you can ensure that the type is public and has a parameterless constructor - all public members of the type will then be serialized, and no attributes will be required.

Я думаю, что он пытается десериализовать DeviceState с помощью отката к DataContractSerializer и не зарегистрированDeviceStateSerializer.

Answer 1

Государственный регистратор сериализатора должен быть в ctor, чем он работает.

public Automat(StatefulServiceContext context)
        : base(context)
{
    var ok = this.StateManager.TryAddStateSerializer(new DeviceStateSerializer());
    if (!ok)
    {
        Log.FailedToRegisterStateSerializer();
    }
}
