Create ApplicationInsight TelemetryConfiguration without config file

Question

I dont know if it's posssible to create full TelemetryConfiguration without applicationInsight.config

I see there are TelemetryInitializers.Add it working well

but nothing for the configs

TelemetryModules (present in config file but not on the class)
DefaultTelemetrySink.TelemetryProcessors (present in the config file but there are no Add method in the class)

I serarched everywhere for an example of complete configuration via code but did not find anything. I want to get rid of the config file, because I want to use the TelemetryConfiguration in a common library. And don't want to pupulate many config files in end up librairies.

I looking in debug mode and seen many differences between class obtained with TelemetryConfiguration.CreateDefault() when I have the config file obtained from nuget package, and the one obtained when I have no config file. This is the reason of my question.

what I have sofar

internal class ApplicationInsightConfig
{
   public TelemetryConfiguration Config { get; }

   public ApplicationInsightConfig()
   {
      Config = TelemetryConfiguration.CreateDefault();
      Config.InstrumentationKey = ConfigurationManager.GetSetting(new ConfigKey("ApplicationInsightKey"));
      Config.ApplicationIdProvider = new ApplicationInsightsApplicationIdProvider();
      Config.TelemetryChannel.DeveloperMode = false;
      DefineTelemetryInitializers();
      DefineDefaultTelemetrySink();
   }

   private void DefineDefaultTelemetrySink()
   {
      var tp = Config.DefaultTelemetrySink.TelemetryProcessors;
      Config.DefaultTelemetrySink.TelemetryChannel = new ServerTelemetryChannel();
   }

   private void DefineTelemetryInitializers()
   {
      Config.TelemetryInitializers.Add(new AzureAppServiceRoleNameFromHostNameHeaderInitializer());
      Config.TelemetryInitializers.Add(new HttpDependenciesParsingTelemetryInitializer());
      Config.TelemetryInitializers.Add(new AzureRoleEnvironmentTelemetryInitializer());
      Config.TelemetryInitializers.Add(new BuildInfoConfigComponentVersionTelemetryInitializer());
      Config.TelemetryInitializers.Add(new WebTestTelemetryInitializer());
      Config.TelemetryInitializers.Add(new SyntheticUserAgentTelemetryInitializer { Filters = "search|spider|crawl|Bot|Monitor|AlwaysOn" });
      Config.TelemetryInitializers.Add(new ClientIpHeaderTelemetryInitializer());
      Config.TelemetryInitializers.Add(new OperationNameTelemetryInitializer());
      Config.TelemetryInitializers.Add(new UserTelemetryInitializer());
      Config.TelemetryInitializers.Add(new AuthenticatedUserIdTelemetryInitializer());
      Config.TelemetryInitializers.Add(new AccountIdTelemetryInitializer());
      Config.TelemetryInitializers.Add(new SessionTelemetryInitializer());
   }
}

Thank you for help!

I think you are on the right track. Setting the telemetry channel could be done slightly different:

TelemetryConfiguration config = TelemetryConfiguration.CreateDefault();
config.InstrumentationKey = ConfigurationManager.GetSetting(new ConfigKey("ApplicationInsightKey"));
config.TelemetryChannel = new ServerTelemetryChannel { DeveloperMode = false };

Telemetry modules all implement ITelemetryModule, which defines a void Initialize(TelemetryConfiguration configuration) method to wire up the module:

var module = new UnhandledExceptionTelemetryModule();
module.Initialize(config);

Telemetry processors can be added using the TelemetryProcessorChainBuilder:

var builder = config.TelemetryProcessorChainBuilder;
builder.Use(next => new AdaptiveSamplingTelemetryProcessor(next));
builder.Build();

Then the final step is to use the config:

var telemetryClient = new TelemetryClient(config);

For those how want te final version here is the code :

//-------------------------------------------------------------
// Transcription code of the default ApplicationInsight.config
//-------------------------------------------------------------
internal class ApplicationInsightConfig
{
   public static TelemetryConfiguration Setup()
   {
      var config = TelemetryConfiguration.CreateDefault();

      config.InstrumentationKey = ConfigurationManager.GetSetting(new ConfigKey("ApplicationInsightKey"));
      config.TelemetryChannel = new ServerTelemetryChannel { DeveloperMode = false };

      //Setup TelemetryInitializers...
      InitTelemetryInitializer(config);

      //Setup Modules
      InitTelemetryModules(config);

      //Setup TelemetryProcessor
      InitTelemetryProcessor(config.TelemetryProcessorChainBuilder);

      return config;
   }

   private static void InitTelemetryProcessor(TelemetryProcessorChainBuilder builder)
   {
      builder.Use(next => new QuickPulseTelemetryProcessor(next));
      builder.Use(next => new AutocollectedMetricsExtractor(next));
      builder.Use(next => new AdaptiveSamplingTelemetryProcessor(next) { MaxTelemetryItemsPerSecond = 5, ExcludedTypes = "Event" });
      builder.Use(next => new AdaptiveSamplingTelemetryProcessor(next) {MaxTelemetryItemsPerSecond = 5, IncludedTypes = "Event"});
      builder.Build();
   }

      new ExceptionTrackingTelemetryModule().Initialize(config);
      new AspNetDiagnosticTelemetryModule().Initialize(config);
   }
