C#实现LSP向VS Code发送初始化响应报错的技术问询

我用C#构建Language Server Protocol（LSP）服务，当前正在配置初始化请求的响应逻辑。服务可以正确接收JSON-RPC消息，但向Visual Studio Code返回响应时出现异常。

相关代码 #

case "initialize":
    var request = new InitializeRequest();

    try
    {
        request = JsonSerializer.Deserialize<InitializeRequest>(content);

        if (request != null)
        {
            logger.Log("Deserialization successful!");
            logger.Log($"ClientInfo Name: {request.Params.ClientInfo.Name}");
            logger.Log($"ClientInfo Version: {request.Params.ClientInfo.Version}");
            InitializeResponse msg = new InitializeResponse("2.0", request.ID);
            var reply = Rpc.EncodeMessage(msg);
            logger.Log("Replying With: " + reply.ToString());
            Console.WriteLine(reply);
            logger.Log("Replied!");
        }
    }
    catch (Exception e)
    {
        logger.Log("Error: " + e.Message);
    }
    break;

EncodeMessage方法实现 #

public static string EncodeMessage(object message)
{
    try
    {
        string content = JsonSerializer.Serialize(message);
        string header = $"Content-Length: {Encoding.UTF8.GetByteCount(content)}\r\n\r\n";
        string encodedMessage = header + content;
        Program.logger.Log("Serialized Content: " + content);
        Program.logger.Log("Header: " + header);
        Program.logger.Log("Encoded Message: " + encodedMessage);
        return encodedMessage;
    }
    catch (Exception e)
    {
        Program.logger.Log("Error in EncodeMessage: " + e.Message);
        return null;
    }
}

日志输出 #

VS Code抛出的错误 #

[Error - 5:00:31 PM] Client Scarbro Script LSP: connection to server is erroring.

Message header must separate key and value using ':' initialize

Shutting down server.

[Error - 5:00:31 PM] Stopping server failed

我之前曾把serverinfo写错为serverInfo，但修正后问题仍未解决。我猜测可能是JSON字段顺序问题（比如"jsonrpc":"2.0","id":0需要放在最前面），但不确定VS Code的序列化是否会受字段顺序影响，特此求助。
