net 6.0 应用程序：尝试登录 Azure Application Insights 时启动时出现 Serilog 异常

Question

我尝试使用 Serilog 从 dotnet 6.0 控制台应用程序登录到控制台和 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，可以构建和演示所遇到的问题：

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;
}

请随意分叉代码并发出更改和拉取请求。

谢谢

Answer 1

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

到

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

Answer 2

我也有同样的问题。如果使用 .net6，请卸载 NuGet-Package Serilog.Sinks.ApplicationInsights 4.0.0 并安装 Serilog.Sinks.ApplicationInsights 3.1.0。至少我的问题解决了。
