.NET Core and TelemetryConfiguration.Active is deprecated

[ravensorb]

Given that is TelemetryConfiguration.Active deprecated is there a new recommended approach to integrating Serilog with AppInsights in .netcore in general and azure functions specifically?

Have created a PR #160 to update the README with further instructions. You can take a look here.

I tried the solution from PR #160 but it gives
"The logger is already frozen." Source "Serilog.Extensions.Hosting"
any suggestions?

@raigol could you post a code snippet?

Program.cs

  public static int Main(string[] args)
    {            
        Log.Logger = new LoggerConfiguration()
        .MinimumLevel.Override("Microsoft", LogEventLevel.Warning)
        .Enrich.FromLogContext()
        .WriteTo.Console()
        .CreateBootstrapLogger();

        try
        {
            CreateWebHostBuilder(args).Build().Run();
            return 0;
        }
        catch (Exception ex)
        {
            Log.Fatal(ex, "Orders API terminated unexpectedly");
            return 1;
        }
        finally
        {
            Log.CloseAndFlush();
        }
    }



    public static IHostBuilder CreateWebHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .UseSerilog((context, services, loggerConfiguration) =>
            loggerConfiguration
            .WriteTo.ApplicationInsights(services.GetRequiredService<TelemetryConfiguration>(), TelemetryConverter.Traces))
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            }).ConfigureAppConfiguration((context, builder) =>
            {
                builder.AddJsonFile("azurekeyvault.json", true, true);
                var root = builder.Build();
                builder.AddAzureKeyVault(
                    root["KeyVault--Url"],
                    root["KeyVault--ClientId"],
                    root["KeyVault--ClientSecret"]
                );

                var isDevelopment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") == Environments.Development;
                if (isDevelopment)
                {
                    builder.AddUserSecrets<Startup>();
                }
            });

Startup.cs

    public void ConfigureServices(IServiceCollection services)
    {
    services.AddLogging(builder => builder.AddApplicationInsights());

@raigol what version of serilog packages do you use? yesterday I installed the latest ones and I could not use this initialization anymore.

.UseSerilog((context, services, loggerConfiguration) => { /*code here...*/})

Currently UserSerilog can accept only parameter of type Action<WebHostBuilderContext, LoggerConfiguration>

The README now shows how to avoid TelemetryConfiguration.Active, so I'll close this, but please see also #156 for some continuing discussions. Thanks!

@Kira-Lappo i'm late to the party but discovered the same issue a while back. For some reason, the overload for UseSerilog that exposes the service provider is only available for the IHostBuilder, NOT the IWebHostBuilder interface. You'll need to migrate your project to use IHostBuilder instead. The good news is that this migration should be quite painless, at least it was for me. IHostBuilder afaik was introduced with .NET Core 3, here's the migration notes: https://docs.microsoft.com/en-us/aspnet/core/migration/22-to-30?view=aspnetcore-6.0&tabs=visual-studio#hostbuilder-replaces-webhostbuilder

if you're interested, i have posted my code in the discussion of ticket #156
