.NET 中 MessagePack 序列化对象到 IBufferWriter<byte> 的问题

调用 MessagePackSerializer 的序列化代码如下：

public class HybridCacheMessagePackSerializer<T>
    (MessagePackSerializerOptions? options) : IHybridCacheSerializer<T>
{
    public T Deserialize(ReadOnlySequence<byte> source)
    {
        return MessagePackSerializer.Deserialize<T>(source, options);
    }
    public void Serialize(T value, IBufferWriter<byte> target)
    {
        MessagePackSerializer.Serialize(target, value, options);
    }
}

使用的 MessagePackSerializerOptions：

public static MessagePackSerializerOptions CreateDefaultOptions()
{
    var resolver = CompositeResolver.Create(
        NativeDateTimeResolver.Instance,
        NativeGuidResolver.Instance,
        NativeDecimalResolver.Instance,
        ContractlessStandardResolver.Instance);
    return MessagePackSerializerOptions.Standard.WithResolver(resolver);
}

序列化时报错：

MessagePackSerializationException: Failed to serialize System.Collections.Generic.List`1[[Cnblogs.Cache.Hybrid.Extensions.Tests+BlogPost, HybridCache.MessagePack.Tests, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]] value.
---> MessagePack.FormatterNotRegisteredException: Cnblogs.Cache.Hybrid.Extensions.Tests+BlogPost is not registered in resolver: MessagePack.Resolvers.StandardResolver

请问如何解决这个问题？

问题补充：

用 ArrayBufferWriter<byte> 测试是正常的

var blogPosts = await GetBlogPostsAsync();
var options = MessagePackSerializerFactory.CreateDefaultOptions();
var writer = new ArrayBufferWriter<byte>();
MessagePackSerializer.Serialize(writer, blogPosts, options);
