问题现象
  • 项目从Umbraco 9升级至Umbraco 10后，启动时抛出异常："Value cannot be null. (Parameter 'logger')"
  • 移除Program.cs中CreateHostBuilder方法内的如下Serilog配置代码后，异常消失：
.UseSerilog((hostingContext, loggerConfiguration) =>
        loggerConfiguration
        .ReadFrom.Configuration(hostingContext.Configuration)
         .WriteTo.ApplicationInsights(new TelemetryConfiguration { InstrumentationKey = hostingContext.Configuration["ApplicationInsights:InstrumentationKey"]
}, TelemetryConverter.Traces));
  • 异常堆栈跟踪：

故障原因

Umbraco 10 重构了内部日志初始化流程，依赖可重载的ReloadableLogger作为启动早期的日志实例，等宿主构建完成后再替换为正式日志配置。
原有代码存在两个问题：

  • 手动new TelemetryConfiguration()创建的实例未完成完整初始化，会导致Serilog接入时提前触发依赖解析，打断Umbraco的日志加载流程，最终传入RegisteredReloadableLogger构造函数的logger实例为null
  • 调用UseSerilog时未开启writeToProviders参数，会覆盖Umbraco默认注册的日志提供器，导致后续框架内部无法解析到日志实例
修复方案

两种方案二选一即可，优先使用配置文件方式，兼容性更好。

方案1：修改代码层Serilog配置

将原有UseSerilog段替换为如下代码，不要手动实例化空的TelemetryConfiguration，同时开启必要的参数保证Umbraco日志流程正常：

.UseSerilog((hostingContext, loggerConfiguration) =>
        loggerConfiguration
        .ReadFrom.Configuration(hostingContext.Configuration)
        .WriteTo.ApplicationInsights(
            // 用CreateDefault自动加载配置中的ApplicationInsights节点，无需手动赋值InstrumentationKey
            TelemetryConfiguration.CreateDefault(),
            TelemetryConverter.Traces),
    writeToProviders: true,
    preserveStaticLogger: false);

如果需要手动指定InstrumentationKey，可以在CreateDefault()后赋值，不要直接new空对象：

var telemetryConfig = TelemetryConfiguration.CreateDefault();
telemetryConfig.InstrumentationKey = hostingContext.Configuration["ApplicationInsights:InstrumentationKey"];

方案2：将ApplicationInsights配置移入配置文件

这种方式完全不需要在代码中硬编码Sink配置，不会干扰Umbraco的日志初始化流程：

  1. 修改Program.cs中的UseSerilog配置，仅保留配置读取逻辑：
.UseSerilog((hostingContext, loggerConfiguration) =>
        loggerConfiguration.ReadFrom.Configuration(hostingContext.Configuration),
    writeToProviders: true);
  1. 在appsettings.json的Serilog节点下添加ApplicationInsights的Sink配置：
{
  "Serilog": {
    "MinimumLevel": "Information",
    "WriteTo": [
      {
        "Name": "ApplicationInsights",
        "Args": {
          "telemetryConverter": "Serilog.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights",
          "instrumentationKey": "你的ApplicationInsights检测密钥"
        }
      }
    ]
  }
}

修改完成后重新启动项目，异常会消失，日志可正常写入ApplicationInsights，同时Umbraco后台功能不受影响。
