Question

在点燃here时询问有关安排作业的问题。

使用简单的文本输出到控制台并通过HttpClient通过简单的异步Web请求对其进行测试。工作良好。

实现了具有大量长时间运行任务和并行计算的实际业务逻辑。

Ignite .NET版本：2.3.0

应用平台：dotnet core 2.0

但是使用DeployClusterSingleton收到服务注册的例外情况。

System.Runtime.Serialization.SerializationException：'序列化这个平台不支持代表。'

很难猜到，造成这种情况的代码部分。我所要做的就是逐个部分替换代码。

如果需要更多详细信息，我可以提供其他信息。

经过调查：

是IOptions<>，ILogger<>

下一个是来自System.PlatformNotSupportedException: 'Operation is not supported on this platform.'

的System.Reflection.RuntimePropertyInfo.GetObjectData(SerializationInfo info, StreamingContext context)

另一个是：Apache.Ignite.Core.Binary.BinaryObjectException: 'Conflicting field IDs [type=HttpClient, field1=_disposed, field2=_disposed, fieldId=375705476]'

遗憾的是，由于这个原因，我不得不改变架构;

Answer 1

此异常是由.NET Core引起的，does not support delegate serialization。 Ignite只需调用标准GetObjectData方法。

这可以在正常的.NET 4 +下工作。

您的服务类是否包含任何代理？

此平台不支持Apache Ignite .NET序列化委托
