错误堆栈如下
System.NullReferenceException:“Object reference not set to an instance of an object.”在 System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage(IMessage reqMsg, IMessage retMsg)在 System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)
System.NullReferenceException:“Object reference not set to an instance of an object.”在 System.Runtime.Remoting.Messaging.StackBuilderSink._PrivateProcessMessage(IntPtr md, Object[] args, Object server, Object[]& outArgs)在 System.Runtime.Remoting.Messaging.StackBuilderSink.SyncProcessMessage(IMessage msg)
具体原因未知,预计是版本之间的兼容性问题,导致某些逻辑/进程跑了不同的 .NET Framework 版本。而多个 .NET Framework 版本没有做好运行时兼容性
