C# 在应用程序池回收后使用MsgPack序列化程序时使用REGDB_E_CLASSNOTREG

我们在IIS 10中托管了一个WCF服务应用程序

每次IIS在不活动20分钟后回收应用程序池时，在使用MsgPack进行反序列化时都会出现以下异常：

The type initializer for 'MsgPack.Serialization.EmittingSerializers.SerializationMethodGeneratorManager' threw an exception. System.TypeInitializationException: The type initializer for 'MsgPack.Serialization.EmittingSerializers.SerializationMethodGeneratorManager' threw an exception. ---> System.Runtime.InteropServices.COMException: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

当我手动回收应用程序池时，问题消失了，一切正常。在发生自动回收事件之前，问题会再次出现

我已经强制所有程序集在应用程序启动后立即加载到AppDomain中，代码如下：

var assemblies = BuildManager.GetReferencedAssemblies().Cast<Assembly>();

var assemblies=BuildManager.getReferencedAssemblys（）.Cast（）；

有人对此有线索吗？

这是一个开源项目，为什么不在GitHub上ping它的开发人员呢？我在GitHub上打开了一个问题，但到目前为止，这种行为还不清楚。。。我想知道为什么自动回收和手动回收有区别。
