c# - NET 6.0应用程序: Serilog exception on startup when trying to log to Azure Application Insights

Question

我尝试使用 Serilog 从 dotnet 6.0 控制台应用程序记录到控制台和 Azure 应用程序见解。我正在从 appsettings.json 文件加载配置。

但是，在启动时，我遇到了异常:

An unhandled exception of type 'System.InvalidOperationException' occurred in Serilog.Settings.Configuration.dll: 'Type Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights was not found.'
   at Serilog.Settings.Configuration.StringArgumentValue.ConvertTo(Type toType, ResolutionContext resolutionContext)
   at Serilog.Settings.Configuration.ConfigurationReader.<>c__DisplayClass21_2.<CallConfigurationMethods>b__3(<>f__AnonymousType9`2 <>h__TransparentIdentifier0)
   at System.Linq.Utilities.<>c__DisplayClass2_0`3.<CombineSelectors>b__0(TSource x)
   at System.Linq.Enumerable.SelectListPartitionIterator`2.ToList()
   at Serilog.Settings.Configuration.ConfigurationReader.CallConfigurationMethods(ILookup`2 methods, IList`1 configurationMethods, Object receiver)
   at Serilog.Settings.Configuration.ConfigurationReader.Configure(LoggerConfiguration loggerConfiguration)
   at Serilog.Configuration.LoggerSettingsConfiguration.Settings(ILoggerSettings settings)

我从 Serilog 网站和其他地方的各种示例中选取了代码。谁能看出我的代码有什么问题吗？

我这里有一个示例程序，可以构建和演示遇到的问题:

程序.cs

// See https://aka.ms/new-console-template for more information
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Serilog;

IServiceProvider _serviceProvider;
ILogger<Program> _logger;


Console.WriteLine("Hello, World!");

var config = InitConfiguration();

IConfiguration InitConfiguration()
{
    var configuration = new ConfigurationBuilder()
        .AddJsonFile("appsettings.json")
        .Build();
    
    Log.Logger = new LoggerConfiguration()
        .ReadFrom.Configuration(configuration)
        .CreateLogger();

    var services = new ServiceCollection();

    services.AddLogging(configure => configure.AddSerilog())
            .AddTransient<Program>();

    services.Configure<LoggerFilterOptions>(options => options.MinLevel = LogLevel.Debug);

    _serviceProvider = services.BuildServiceProvider();

    _logger = _serviceProvider.GetService<ILogger<Program>>();
    _logger.LogInformation("Logger initialized!");

    var loggerFactory = _serviceProvider.GetService<ILoggerFactory>();
    _logger = loggerFactory.CreateLogger<Program>();
    return configuration;
}

appsettings.json

请随意 fork 代码并发出更改和拉取请求。

谢谢

结果 Serilog telemetryConverter 的 appsettings.json 文件类型名称已更改为:

Serilog.Sinks.ApplicationInsights.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights

至

Serilog.Sinks.ApplicationInsights.TelemetryConverters.TraceTelemetryConverter, Serilog.Sinks.ApplicationInsights
