排查与解决方案 #

1. 升级Application Insights SDK版本 #

你使用的Microsoft.ApplicationInsights.AspNetCore 2.21.0存在已知的TelemetrySink释放后调用的bug，后续版本已修复。建议升级到2.22.0及以上版本，优先选择最新稳定版。

2. 修正日志调用方式 #

当前代码中_logger.LogError("PurchaseTransactionData", dto)的调用不符合日志API规范：LogError的第二个参数应为异常对象，而非自定义数据。错误的参数传递可能触发内部序列化异常，间接导致资源释放问题。改为结构化日志写法：

// 结构化日志，便于在Application Insights中查询分析
_logger.LogError("PurchaseTransactionData: {TransactionData}", jsonString);

3. 同步升级Service Profiler包 #

Microsoft.ApplicationInsights.Profiler.AspNetCore需与Application Insights SDK版本兼容，升级SDK后建议同步升级Profiler包到匹配版本，避免版本冲突引发的资源生命周期异常。

4. 确保日志操作在请求生命周期内完成 #

检查是否存在请求返回后（如Ok(jsonString)之后）触发的延迟日志逻辑（比如后台任务、异步回调），这类操作会在TelemetrySink已被释放时执行，导致报错。所有日志操作应确保在请求处理流程内完成。

5. 显式配置TelemetrySink生命周期（可选） #

若升级后问题仍存在，可显式将TelemetrySink注册为单例，避免提前释放：

services.AddApplicationInsightsTelemetry();
services.AddSingleton<ITelemetrySink>(sp => sp.GetRequiredService<TelemetrySink>());
services.AddServiceProfiler();
