Bug: failed System.TypeLoadException #54

Closed mirbeta closed 1 year ago

mirbeta commented 1 year ago

The HostOptions.BackgroundServiceExceptionBehavior is configured to StopHost. A BackgroundService has thrown an unhandled exception, and the IHost instance is stopping. To avoid this behavior, configure this to Ignore; however the BackgroundService will not be restarted. System.TypeLoadException: Virtual static method 'Serialize' is not implemented on type 'SystemModule.Packets.ServerPackets.ServerDataMessage' from assembly 'SystemModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Thank you. I've understand issue. NetStandard 2.1 class library can not use from Net7 application. This is because the .NET 7 version uses static abstract members that require runtime updates. You need to update library to Net7(or use TargetFrameworks netstandard2.1;net7.0).

This will be noted in the ReadMe, as the error is not easy to understand. Thanks.

Maybe this needs to be fixed by the .Net team? it is very common to use netstandard2.1 in shared libraries, maybe we will see netstandard2.2 in the near future? Not all teams or developers will use net7 or higher to solve problems usually use libraries.

Thank you again, the error has been fix using net7 as you said.

Library developer, configure dual target framework. <TargetFrameworks>netstandard2.1;net7.0</TargetFrameworks> Applicatoin developer, only to use net7.0. <TargetFramework>net7.0</TargetFramework>

https://github.com/Cysharp/MemoryPack/blob/main/src/MemoryPack.UnityShims/Shims.cs When the server uses Vector3 in Shim and the Unity client uses UnityEngine.Vector3, the value of the Vector3 uploaded by the client is not parsed correctly on the server side, is this the correct behavior, because UnityEngine.Vector3 is really not tagged in Unity as [ MemoryPackable]
