Protobuf.netexception – 检查元数据时超时

尝试使用protobuf.net反序列化对象时，有时会收到以下exception。我很惊讶，因为我从来没有多个线程同时反序列化同一个对象，并且protobuf.net源似乎没有使用任何静态对象进行反序列化。 exception确实提出了一个解决方案，但我不确定如何实现，所以欢迎一个例子。

Base Exception Type: System.TimeoutException: Timeout while inspecting metadata; this may indicate a deadlock. This can often be avoided by preparing necessary serializers during application initialization, rather than allowing multiple threads to perform the initial metadata inspection at ProtoBuf.Meta.RuntimeTypeModel.TakeLock(Boolean& lockTaken) at ProtoBuf.Meta.RuntimeTypeModel.FindOrAddAuto(Type type, Boolean demand, Boolean addWithContractOnly, Boolean addEvenIfAutoDisabled) at ProtoBuf.Meta.RuntimeTypeModel.GetKey(Type type, Boolean demand, Boolean getBaseKey) Inner Exception Type: System.TimeoutException: Timeout while inspecting metadata; this may indicate a deadlock. This can often be avoided by preparing necessary serializers during application initialization, rather than allowing multiple threads to perform the initial metadata inspection at ProtoBuf.Meta.RuntimeTypeModel.TakeLock(Boolean& lockTaken) at ProtoBuf.Meta.RuntimeTypeModel.FindOrAddAuto(Type type, Boolean demand, Boolean addWithContractOnly, Boolean addEvenIfAutoDisabled) at ProtoBuf.Meta.RuntimeTypeModel.GetKey(Type type, Boolean demand, Boolean getBaseKey) Stack Trace: at ProtoBuf.Meta.RuntimeTypeModel.GetKey(Type type, Boolean demand, Boolean getBaseKey) at ProtoBuf.Meta.TypeModel.GetKey(Type& type) at ProtoBuf.Meta.TypeModel.Deserialize(Stream source, Object value, Type type)

此致，马克

编辑添加：我定义了我的可序列化对象：

[ProtoContract] public class Job { [ProtoMember(1)] public long JobId { get; private set; } }

我很难在每个可序列化对象上轻松调用PrepareSerialiser，因为我在不同的命名空间中有很多。但是考虑一下如果要求protobuf对同一类型的两个对象进行反序列化会发生什么呢？这个对象之前没有见过，类似于同一时间？
