How to configure TelemetryConfiguration without dependency injection?

Question

I use Application Insights in a webjob. Current I don't use dependency injection. I need to configure the TelemetryChannel to be able to Flush the provider before exiting my webjob. Is it possible to configure/set/inject the TelemetryConfiguration into the logging provider for App Insights without DI?

I use the following statement to add the logging provider.

    builder.AddApplicationInsightsWebJobs(o => o.ConnectionString = connStr).SetMinimumLevel(LogLevel.Information);

Answer 1

configure TelemetryConfiguration without dependency injection?

To Configure Telemetry without DI, we need to pass Instrumentation Key or ConnectionString to the TelemetryConfiguration.

I have tried to set the Keys from appsettings.json

Install the NuGet Package Microsoft.ApplicationInsights.Web.

My appsettings.json file

{
  "Logging": {
    "ApplicationInsights": {
      "LogLevel": {
        "Default": "Debug",
        "Microsoft": "Error"
      }
    },
    "LogLevel": {
      "Default": "Information",
      "Microsoft.AspNetCore": "Warning"
    }
  },

  "AllowedHosts": "*",
  "ApplicationInsights": {
    "ConnectionString": "****",
    "Instrumentationkey": "****"
  }
}

Thanks @rogerpence.dev for the code snippet.

I have tried to follow the given code but got the below error.

 var config = new ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json")
.AddEnvironmentVariables()
.Build(); 

For now, I have set the keys in Program.cs file itself.

Is it possible to configure/set/inject the TelemetryConfiguration into the logging provider for App Insights without DI?

In Visual Studio, right click on the solution root folder => Add => Connected Service.

• Add Application Insights service dependency .

My .csproj file

<Project Sdk="Microsoft.NET.Sdk;Microsoft.NET.Sdk.Publish">

    <OutputType>Exe</OutputType>

We have MSDoc which explains Configurating Telemetry without Dependency Injection.

Program.cs

using Microsoft.ApplicationInsights;
using Microsoft.ApplicationInsights.DependencyCollector;
using Microsoft.ApplicationInsights.Extensibility;
using System.Net.Http;
using System.Threading.Tasks;
using static System.Net.Mime.MediaTypeNames;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {            
            TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
            configuration.ConnectionString = "Copy the Connectionstring from AppInsights";
            //configuration.InstrumentationKey = "****";
            var telemetryClient = new TelemetryClient(configuration);
            telemetryClient.TrackTrace("Hello World!");
            telemetryClient.TrackTrace("This is the Telemetry Logs!");
            telemetryClient.Flush();
        }      
    }
}
